I am brand new to this forum and I don't know if anyone has already started a thread but I would love to see some of the other spas out there and especially anything custom or modded. We have a removable LCD TV / DVD combo that I can quickly put on a swing arm for ball games and movies which is a great way to go. You can run the audio out from the TV right into your radio so the sound plays through your speakers if you want to get a little custom.
My next move is to put an XBOX360 close by and figure out how to waterproof the wireless cotrollers with some custom silicon O-rings. We want to play Madden and not have to worry about the controllers getting wet. The XBOX360 Arcade model just dropped to $199 and would be perfect for this.
I'll post some of my own pics sometime tomorrow.
