First time E-Reader!

I used to be all for physical copies of books, and I still am, however I go through books very quickly. I graduate this year and have plans to do a lot of traveling, and having physical books with me at all times is both space consuming, and money consuming. An E-reader is such a compact way to keep all my books on me!

However, I don’t know what models are best, affordable, and reliable. I do not want to get a kindle since I do not like the feature where they can take your PAYED books away at any given time, so I’m looking for one that is of a different brand.

Suggestions?
