I just ordered some on friday for $162 (and $8 for new gaskets). the clear sides were $26.
they also have great deals on covers, if you're in the market...got a solverguard cover for $121.
they price at supposedly cost plus 15%...and the service was awesome, and the shipping was reasonable. I olmost ordered from suncoast until I saw how much they wanted for shipping (they tack on a few bucks there).
