Hi Caleb and welcome to MR.
Hard choice to make with more and more readers coming on the market. Best would be to make a list of what you want from it first. Then start looking at what is available. The wiki link is a good start.
Don't wait for the perfect reader - it doesn't exist and probably never will. And you just end up without one. And lets not forget that they are a consumer product, not meant to last the next 50 years. Yes, they are expensive atm but you will save some money if you are an avid reader and currently buy a lot of books.
For me a reader is the perfect choice when you travel a lot (including to work) as it saves you lugging around a book or when you are short of space for keeping all books.
I love my Sony PRS600 - I bought it before I knew all the different things I know now. And maybe I would make another choice today. But it got me started and with the help of MR I am utilising it.
So, have a look and take the plunge.
