I'm glad I bought this little guy as camcorder
Enjoy it - it's a great series, IMO.
I looked at the M52, and I was actually a little puzzled compared to its predecessor, the M41.
I like the idea of better low-light sensitivity (Canon claims a 20% improvement, although that's linear measurement - in photographic terms, that's a little less than 1/6-stop). But while both have 32 GB internal memory, the M52 lost one of the dual SD slots, and more significantly, it lost the EVF that the M41 has, which is great in bright sunlight.
I have the M41, and it's a great little camcorder. I've also got the mini-hotshoe video light and the directional mic. If you're looking for a bag, the Lowepro Edit 100 is a good fit.
