HUGE VOUCH for Frubar - Sold him a base 80 stat pure & I've been renting my main account out to him for a few weeks now. Never had an issue when asking for payments & I even went first on the pure sale.
Generic quote but I genuinely do think that he's one of the nicest people I've met in my RS career & I look forward to continued business with him, providing that his potato of a PC isn't served for dinner ;p
