There really does need to be a recording forum.
I have the q8. Really dig it. Very good audio from stock xy mic, plus two additional mic/line inputs make doing live recordings painless. If you are good with a daw, it's particularly good. Get a 64 gig card, and you'll have hours of video with separate audio tracks to mix later.
My band mate uses the 16 track all-in-one recorder, with great results also. That is a great way to go if u want the channels.
There's a bunch of places. But I meant more here. There's more and more topics on the subject, many of them the same, and they're strewn about multiple subforums.Homerecording.com has an excellent Drums and Percussion section that can answer these questions really well.
