Personally, I greatly value ALL pictures, comments of gens and comparisons of reps to them...Especially in the Panerai forum. Since the currently available PAM rep models aren't the most accurate reps around, it's these gen comparisons that lead to the excellent projects that members on this and other boards come up with to make 1:1 (or at least damn near) parts (V CGs, T crowns, FGD dials, LH dials, just to name a few).
Isn't that what this hobby is all about?
And as far as price for gen or rep parts goes, my opinion is that if someone wants to make some money off of what they own or what they create, more power to them...If the market wasn't there, nothing would sell.
Just ask V how many CGs he has left, or ask FGD how many dials he has left. The seller only sets a price. It's up to all of us if we want to pay that price. Why begrudge the seller? Doesn't make much sense to me.
