Two months ago I lost my Tascam DR-05, and maybe it was a sign to look for a better recorder... besides being a bummer!
Anyway, everyone has their favorites, so this is not a discussion I'm willing to start. Things I want are:
1) Good quality, usable XLR mic preamps.
2) At least 96KHz wav recording.
3) Reliability, as some Tascam models seem to have hum with DSLR cameras (DR-60 and DR-70)
4) Price is an issue, of course, so higher priced types (>$300) are out
