Thanks for the detailed reply Dean, I have been looking for used ones on the Internet mainly just for the frame it's self and the ones I find in the UK are the chinese ones and some have been used a few times or some only use them once or twice a week for a few hrs, makes you think why they are getting rid and now I know.

I seen a post the other day with a large 8x4 frame on Google got all excited as it looked beafy and it was only £200, turns out it was in 2015 was gutted lol
