I'd say you done alright there based purely on the frame & forks alone, it looks in mint condition. Does look like its been built up using a load of crappy burner bits & anything else the previous owner had laying aroud, chances are that the frame & forks if they had been sold on their own would have fetched the same money. My advice now would be to strip all of them crappy parts off & put them on ebay as a sold as seen job lot, if you got £20 for the lot it would make the frame & forks even more of a bargain, then set about sourcing some nice bits, good luck mate, I hope it turns out well
