yep, the POD Studio Interfaces are pretty good - the software sounds very good and you'll get great results fast - recommended
meh, it's an ok product...they are USB 1.1 though so keep that in mind.
Also see the post with the guy having issues with his new UX1.

I personally never had luck with the Line6 interfaces.
The old software was ok sounding as well...nothing great. Not sure about the new stuff.
