It's just not the same. The PIV is the daddy of zorro gfx cards, mainly because it has a FF/SD that is of such good quality that it is my opinion that it is unequalled.
There are several pieces of Amiga hardware that always fetch a good price because they were good back in the day and they are still good now:
1) Cyberstorm PPC
2) PIV
3) DKB3128
To some extent the other Cyberstorms are also highly valued. There are other items that are just rare. If a Fastlane Z3 with 256mb capability ever goes on ebay I suspect that will fetch a boatload of bucks. Many of these bidders are guys just tinkering around with classic Amigas as a hobby. These guys may not have had the bucks to get these add-ons at the time, but now they do and they are willing to pay for that (I fall into that group). I bought most of my upgrades well after the Amiga had no practical value in terms of a home computer (for me).
But here I am still buying Amiga hardware. I guess that hardware is worth what I am willing to pay for it. And the bottom line is a PIV is going to be worth more than any other zorro gfx card, to me.
