Wanted – used MTB for friend (budget £300)

My mate Mark is due back from Brazil in July and is looking to buy a basic but descent used MTB, rather than hiring a bike everytime he is back. Budget is about £300 and for that the bike must be simple but good condition with no imminent repairs! size 17-18 inch, hardtail, v-brakes preferred, basic – but not too basic (i.e. entry level rockshok) fork. His old bike was a mid-range Trek which he liked, not fussed about make though – so if anyone knows somebody looking to offload something reasonable, let me know – ideally with a pic that I can email to him.

Cheers, Stephen
