Me being me, I have to curve your question.......................
Are you planning on getting more balls??
How much are you looking to spend?? (one persons "cheap" is not the same as another)
If you are planning or there is any chance of you getting more I would get a VE-200 from Reptile Basics and they will even build the flex-a-watt for you for free all you have to do is buy the parts![]()
