Can anyone recommend one? I've only found a couple so far but they look like crap. Not only do they want payment for the program, but it seems they want me to buy any ebooks I have through them.

Does anyone use one of these that will let them read ebooks that they already own in text format or otherwise?

I tried searching the forums but just got a bunch of results about facebook and stuff. 

What do you mean "tanx?"
Have a recommendation?
