Do it yourself

First thing to do is run the thing and see if its worth putting any money into. If thats okay then the fix-up is no big deal. You can clean and lightly sand the inside of the tub and put another coat of gel coat on it and replace some tiles along the top. Considering the prices of these thing new, you may have a deal. Oh yeah, check the heater out, a new element is about 50 bucks. But most of the time the wiring might need some cleaning up. If you need to replace some pvc use Oatey Rain or Shine as a cement. Any more questions ,,let me know,,,,been there, done that.
