That will do for me. I'm sold. 
I said wow earlier to the G220 for £125, I didnt realise it was £129 brand new. So they defo hold their price well.
Seems on that detailing world site there's a guy that gives group lessons with the G220, think I'll benefit from it if I grab one ?
Yeah thats what i mean, you cant lose if you get one and look after it!
Davek i think, yeah. I dont think so really with the dual action, maybe a rotary as you can do damage with one of those. You would be better off get a nice scrap panel from a breakers, scratch it up and teach yourself as you need to feel it and pick up things on your own. Took me a year to get perfect with mine mate working on various paints an learning best pad/polish combos.
