Thanks a lot for the advice guys! Maybe I'm focussing on the specifics too much and what I really need to do is just buy one haha!! I'll keep an eye out on the second hand market like you suggested Meanwhile and see if I can pick up a bargain. If not I'll buy a new one. I will check out that link Meanwhile! I live in Glasgow and Evans have two big stores here. I think I'd be keen to buy from them just for the services and customer support as apposed to halfords!
Great advice, and great forum! I'll post here again.
Cheers
