This is probably more relevant to UK/EU members as I'm sure US prices would be cheap as chips. I have the option to acquire a Pentax 6x7 with a 105 and 200. Everything works fine and the glass is all clean, the body has seen better days and has an unmetered prism and the 105 has a small bit of wood missing from the M/A switch. So basically it looks rough but works. The seller asks for £300, is that fair or would £200-250 be more like it (£200 is probably too low?).
As long as it's the MLU version, and that the lenses aren't the earliest versions I think it's a fair price.
I've sold two pentax 6x7 kits in the past year, one with a 105mm f2.5 and the other with a 90mm f2.8 both with unmetered prisms, and both fetched around the 300 pound mark on eBay.
Yeah I now think £300 is probably a bit much considering that this is the very first model and looks pretty beat up. I'll see what's available, may still go for it if they drop the price to 250 or less.
