Factor in your time searching for the best price -

I'd say $1000 is pretty good. I paid $799 for my Dolphin a few years ago with a 20% off coupon at Leslie's Pool (in-store).

They have a 20% off deal right now on pool cleaners (until the 13th of May I think). It's supposed to be a coupon only deal - but you probably could get the deal in store from a hungry sales person. I would imagine that would put you in the $1000 range for the Dynamic.
