Finding Nismo

Hey all, I'm thinking of selling my current car (STi) and getting a R33 GTR. I have a budget of around $38,000 - $42,000 and was wondering how hard it would be for me to find a clean R33 GTR in pretty stock condition with this budget. Was looking at R34 but I don't want to get another loan, its a bit out of my price range. Cheers
