Hi, welcome to MR from the Netherland.
I have two Kindles with free 3G (also something to consider) and a good Amazoncustomerservice. There's also lots of people at MR with Sony's, Nooks, iPad, Pocketbook, iPhone and what-not, that are extremely happy with their ereader. It's also a personal thing and depends on what your priorities are.
There's a lot of info about ereaders to be found on MR, also we have free classic ebooks and an informative Wiki. Have fun choosing and enjoy your ereading.
