its a shame to see someone fall out with someone on retrobike,
personally i have brought a stem from him which was described okay so no problems there.
as for the buying stuff and selling it for a profit........... well there are plently off people on here that do that !! even some moderators !! and as for paying over the odds for stuff, well if you are stupid enough to pay for it, then its your own fault.
one of my first buys on here was for a frame that was overpriced, i believed the seller on his price guide and paid the money it also had issues with chips and unmentioned filler but thats the way it goes ! .
it turns out that it wasnt worth the money i paid but hey.... i know for next time. Smile
