I had decided to purchase a C50 based solely on reviews I found online. Found a bike for sell in the paper, called him, it was an M50. Had never heard of it. So did a quick lookup on the M50 and found that it actually was more liked by owners than the C50. Went and looked at it, rode it, LOVED IT, bought it. Came home, found this forum and just continue to be so pleased with my purchase. I have put about 900 miles on it since i got it. I paid $5k for my 2006 model and it had 1100 miles on it. It was still completely stock and looked like it did the day the guy bought it so I have had to spend xtra $$$ putting goodies on it, but hey, that is part of the fun
I say get an M!!
