I picked up an FT-4 on Ebay last year. It cost me a fair shade over $50! I'd jump at the deal for either of them for that price, or even double it.
Mine has already paid for itself. I'd never sell it. If it is ever on the market again that'll be because I'm dead, or it was stolen.
Park should make some more of these unobtanium tools. The fact that they refuse to, at any price, shows me what kind of company they really are.
