Buy a secondhand machine

I'm a beginner so I want to buy a secondhand machine, so I can practice on it and get the hang of things. I would like to buy a basically common machine so that when I have a go for real I'm going to be able to find one of them out and about.
I have done search and found a Hill Billionaire with a bit of luck but people say that it is not the best machine for getting results on.

I would appreciate any advice. Thank you!

That is what I'm doing. I usually get a new machine once every 3 months. The price will range dependant on how old the machine is and which manufacture. For example, a Hi-Flyer would cost me around £500, whilst a Jekyll & Hyde would set you back into 4 figure sums at around £2,500!

Best thing to do, is find a small private club somewhere, see what machines they have in, and than rent or purchase that same machine from a small supplier.
Hope This Helps,
Moss
