I'm Using the Galaxy 5 Player...
and loving it. Root is straightforward if you use Zergrush and there is almost no bloatware. It's also very snappy to respond and the battery life is great - I get 24 hrs+ with light use and more than 10 hrs playing media (movies/surf the web, etc. ). And don't believe the reviews about build quality - this thing is well built and at the same time nice and light to hold - no wrist fatigue at all. One thing to watch though:
The three soft buttons on the bottom turn on after a screen touch so if you are using an ebook reader relying on page flipping by screen touch they will be extremely annoying at night!
I got around this by using Moon Reader in autoscroll mode
