I just wanted to comment on how pleased I am with this thing. The V3 doesn't add that much more - this thing sounds awesome line in.
But the huge advantage is the battery life - absolutely amazing. I recorded almost 11 hours this weekend (phish Hampton) + transferred all files twice, the second time falling asleep and leaving it hooked up by USB overnight - all on ONE set of AAs and it still shows 3/4 full! I use to worry about battery life with my 702, but this thing is a champ. Absolutely killer recorder. IMHO the best of all worlds. If I could, I'd buy another 702 in addition to this, but if I could have only one, this will definitely be it.
