I've got the Nex II (non-e) and while it's got good sound quality, the build quality leaves something to be desired. It's a pain in the ass to get the batteries out and sometimes when I first power it on and play a song, it'll skip the first 20 seconds or so. A reboot fixes that. But other than that, I've been pleased with it, it allows me to reuse the CF cards and AA NimH batteries I bought for my digital camera.
