I will not get a RH1 because the main reason that makes me want to upgrade is Sony's great transfering program SonicStage...
I have Soundman OKM II Rock microphones with Soundman A3 and I'm very happy with it.
I guess I'll get a R-09 for 2 reasons.
1) for Festival taping
2) for 48Hz / 24 bits recording
yeah, of course, rechargeables+high resolution recording are 2 pro´s for the r09.
keep in mind you need at least 3 or 4 "4GB-SD-(HC)" cards for festivals of 2 or 3 days.
24bit/44.1kHz =>4h13min on a 4GB card.
24bit/48kHz=>3h55min on a 4GB card.
for a 3 day festival with 8 hours taping a day this makes 24 hours => so you need 6 x 4GB sd cards.
using an h120 or h140 you need an external battery-pack(USB) or you charge your iriver while sleeping(full charge takes about 3 hours).
on a h120 in 16bit wav you can record 3h23(2GB)x9=>~30-32 hours.
