Help on buying a camera to record my live by Dimitrios Angelakis

I want to buy a camera that has a descent audio and video quality in order to record my gigs. I know that zoom Q3 HD and zoom Q2 HD are pretty good models. I also want to be able to connect the zoom with the mixer and also plug in an external microphone.
Any suggestions?
Thank you

they're probably good. i would get the one that streams live. i bet it's the q3.

I think the one that streams is the q2

HD needs A LOT of memory, and if the Q3HD didn't change since last year, I doubt you'll be able to record a full gig, or even a full set.... I own a Q3 (non HD) and using only the audio (thus using much less memory), I can record almost a gig with good audio definition. With low definition I can record hours and hours.
Hope that helps...

I wonder if I can put an extra memory card???????

you can put a larger memory card in it. it will come with a small one. so you'll need money for that!
