Hello mishagam and welcome to MR.
Check out the forum '
which one should I buy' which also has a
comparison matrix in the wiki. Once you narrowed it down, visit the subforums for more info. Or post a question if you can't find the info you are after.
Also check out the
eBook library from MR. Sooooo many free books, lovingly formatted by MR members. That'll keep you reading for a while.
And don't forget to look into the
Lounge if you want some fun.
