Waiting to find an XF100 or XA10 in stock anywhere, in the meantime I've been looking at getting a 2nd small handycam for family events, and the more I see the footage from the new Canons the more impressed I am, low light looks very nice. This fellow did a nice job showing off the low light performance of the M41.

I've seen both and I can't wait to get my hands on an HF M406 (that's the European version of the M400)

I'm sure it's going to be the Low Budget Low Light King.
