It's a valid question for here. I had the HCMW, which I think is the pulldown version of the HCCV. I'm not sure if there is any gain difference between them or not. I thought the image on the HCMW was a little grainy on my AE500, and switched to the Hi Power. I like it better. I never did get to try it with my L300U, so I can't give you an accurate comparison. There are plenty of people who love it though, so I would not be overly concerned.
