Hi,
i bought 8gb, 2nd gen Touch, last month and yesterday updated its software to vers. 3.1(£2.99) I believe this now makes it exact same machine as the 'new' 8gb Touch.
It's amazing piece of kit, but being only 8gb, you'll prob sync lossy(aac, mp3) rather than lossless files, and movies/video will likely use use up it's capacity pretty quick!
The 32gb Touch is now officially £229.99(i'd imagine you'll find it £200 or less) I'd advise you to consider what(how much) you'll be syncing to your new machine!
