Looks like the pool and spa posters have given you some good ideas.

My friend has had a 30" Sony Wega Flat Screen CRT TV for 12 years now and leaves it unlocked in his pool area. I would suggest find the same TV or similar type on Craigslist or through a friend or acquaintance for "free". Currently, electronics stores and disposal sites charge around $20 to $150 to take it off ones hands. Plus, they weigh enough that they cannot go more then a 30 feet without having to put it down.

Just "do not by the HDTV model TV" and you will not have to worry about "anyone stealing your TV". Have your electronics be the analog AV type receivers. They are out of favor like the CRT TVs and are safe to have them outside. They too weight around 35-45 pounds and will not be carried away without having two or more people. There is no market for analog like there is no market for CRT.

Hope this helps.
