Anyone familiar with this site for Dolphin?

I just bought a Dolphin Diagnostic on Ebay. It took about a week to find an auction that didn't go over my pre-set price, but I now have a brand new Dolphin delivered to my door for less that $550. There are several "ebay stores" selling Dolphins, so do a little homework and pay attention to the feedback rating. My experience was great though.

By the way, absolutley love it so far. It's amazing how much crud it will filter out of the water when it looks "clean".

Wow-550 seems to be a great price. I saw an Aquabot at BJ's today for 899. Comes with an extra filter bag and line float and something else. It did seem too heavy either. Leslie's had Dolphin for 799 I think it was. Much difference between the 2?
