I am considering this suction side cleaner to replace my Sta-Rite Great White. Any opinions on the Polaris? Any Polaris ATV users out there? Does anybody know why it's called the ATV now and not the 340?

I also noticed Costco is selling the Dolphin Dynamic, with remote and caddy for $929. This seems like a pretty good deal. I did notice there are more than a few unhappy Dolphin owners out there.
