What camera are you using for "B" roll
 

What camera are you using for "B" roll and/or to compliment your XF30x? If I were to purchase XF30x, it would "break the bank" and leave me in need of a second camera. I currently I have XHA1 (with FS-4HD), HV20 & HV30, which I don't know if they would mix well with the XF30x. What would be a good 2nd camera? I'm thinking something like Sony NEX-VG10, Panny HMC-40, Canon HF-S21 or Sony HDR-XR550V, in that order. Any thoughts, comments and/or anyone with real world experience?

If I didn't want to "break the bank", I would go with a canon t2i along with a 50 1.4. Later on I'd probably pick up a nice zoom.

I've been using a hacked GH1, and it cuts well - especially when finishing at 720. The GH1 looks sharper than the Canon DSLR's, which are a little too soft to cut well with the XF camcorders (IMHO). Also, it doesn't suffer from the colored moire patterns.

I think any of Canon's newer flash-memory consumer camcorders would look good, as long as the limited pro features weren't a bother for you.
