to shed some light on a few things in here:
the power issue - this thing takes the same adaptor as the UA-5, thus it will be powerable by our friendly walmart units (unless im horribly wrong).
2 gig limit - from my understanding this is a softwar/drive format issue, not a wav issue. 4 gig maybe wav limit, but ive certainly recorded wav's over 2gig without issue (i think my longest continuous wav yet is around 1:40) and all that with audacity (FREE!). so yeah, 2 gig is a wavelab/non NTFS thing.
tell me if im wrong on either front
