That sounds horrible, Stormflame. I'm sorry you got ripped off.
My experience was thus (the good, the bad and the ugly):
I went with AuthorHouse. I didn't look around at the other self-publishing alternatives nearly as much as I probably should have, and in retrospect, I would have shopped and compared prices more. However my initial fees with them totalled just over $1400. This included registering with the Library of Congress, copyright registration, distribution through their site, Amazon, B&N and others, and set up of the actual text and cover. I did my own cover design and they let me, which was a creative plus, although their price includes a cover design by them if you wish.
The actual typesetting and galley process was fraught with errors on their end, and it took forever to get them to create an acceptable galley. This didn't raise the cost, but it was time consuming and aggravating. I dealt with at least 7 different "account managers" before I finished. Apparently the turnover of staffing at AuthorHouse is huge, and with the exception of the last one I had, most were incompetent. But, you get what you pay for, so be prepared to insist on satisfaction and to practice patience.
$300 of this $1400 was for their "standard promotional package" which I feel was almost completely wasted money. They wrote me a terrible press release (they even misspelled my main character's name in it) which I had to discard and rewrite myself and with the help of a friend of mine who worked as a professional publicity person. If I had it to do over, I'd simply do this on my own. Their press release distribution also yielded no responses from the press at all. This fee covered their supplying review copies of my book to reviewers when they are requested however, and AuthorHouse has been doing that without hesitation, so perhaps it was worth it anyway. I'll say the jury is still out on that one.
I had one extra charge of about $250 near the end of my galley process because I made my own last minute editorial changes, so if you self-publish, be sure you are COMPLETELY locked in with your text beforehand or you will run up extra costs.
Here's the upside for me going this route:
1) It didn't cost me very much. (In my opinion.)
2) My book looks and reads exactly as I wanted.
3) I have world-wide on-line distribution.
3) I could sell my book in my own way without interference or argument.
4) For me, it has been a foot in the door to becoming a known author (but I've had some lucky breaks, so this is not a given).
The downside:
1) There is a deeply rooted prejudice against self-publishing within the literary community, so be prepared to deal with it. Reviews are hard to get and it takes a lot of extra work to get your book read. I discovered that most major newspapers and publications have blanket policies prohibiting the review of self-published books (this info is through a friend that works at The LA Times). Is it fair? No, but it is the reality self-publishers face.
2) There are no guarantees of return on your investment. You should really look at it as money out the door that you will never see again. I saw it as buying myself a gift rather than a way to make money. If the sales yield some money, great, but don't count on it to make you rich or to even break even.
3) EVERYTHING falls on you. You have to do it all. The self-publishing companies will not be able to sell your book for you, no matter what they claim. You are one in a vast sea of unknown and ignorable "writers."
I think what has worked the best for me was my website. Making it unusual and entertaining has gotten it listed all over the net, and has worked as a nice calling card with potential reviewers and the public. My site still gets around 150 visitors a day and has had days where it has been in the thousands. I had the benefit of being able to animate and put on a show there, so if you want to go this route, I recommend finding extrordinary ways to draw people to your book or site. Despite the popularity of my site, it has not directly translated into massive book sales yet. (It has built a lot of awareness of the book and me, however and definitely helped me get reviewed.)
I also did this in the hopes of eventually being published legitimately, more as a stepping stone rather than an end unto to itself. Self-publishing doesn't get you into bookstores where the bulk of book sales are made. Internet sales are climbing, but if you want to sell lots of books, you need to get a big publisher with clout.
My book has only been out about a year, so I'm still just at the start.
