Hi Mark, i would be happy to loan one to you to try if you was nearer or we could do it at a show, but the last one i lent to someone,..........well lets just say 3 years ago & still waiting to get it back!LOL So im happy to lend one but only if we can meet or show etc,
I can sell you one if you want £70.00 or i can give you the name & number of a guy that can repair them for £100 , but you do get a 3 month warranty.
