I had a polaris 380 with booster pump for years, it worked ok. The problem I had was a line under the cement deck started leaking. It was going to cost me over $1,000 to have the deck cut, the line fixed, and the deck fixed. I scapped it at that point, and it was the best thing I ever did. To run it I had to have the regular pump and the booster pump running - what a waste of electricity.

I bought a Blue Pearl and it is simply amazing. Its filter bag polishes the water better than my DE filter. It climbs the walls and takes out all sorts of stuff. I love it.
