Just bought an HV10
 

I was blown away by the footage from this little camera. Looks waay better than my DVX and GL2.. Ordered it from Norman's for $599..

There's gotta be a catch right? This camera can't be this good for the size and price?

What is the largest battery one can purchase for this camera?

I'm not an expert, but
 

I got an "Impact" rechargeable battery pack,
the IMBP315.
It is supposed to last 2 hours
I think.

the catch is that it doesn't have an audio line in...if you don't care about the audio issue, it's a fantastic purchase.
