I will add that if you can build one yourself and have a reasonable technical ability go for it.
I am very proud to show mine off and my ball driller was amazed how good it works. He has a tub spinner and cost him a lot over here in the UK and its not as sturdy as mine.
I just think if you are good at DIY then it gives you a lot of pride to build something that others cant even buy.
The ball spinning off thing was fun as well, something everyone should experience at least once


Good, fast hands helped.
