I've been look at getting a new bike as my current ride is getting pretty old and knackered, and thought 2nd hand bikes could be a good option as I don't have too much to spend at the moment.
I have found a few promising bikes on ebay, but is there anywhere else to look for 2nd hand bikes? And any comments on buying a 2nd hand bike in general?
I'm looking at hard tail mountain bikes, around the £200-250 mark (can go higher, but lower is better ).
