I bought this Apollo 1260 card on eBay, sold as working, but was not able to get it running on my amiga 1200. I have had problems with other cards on my A1200 tho.
But Since I did not get it running, I can't promise anything.
If it runs on your amiga 1200, then you have a cheap card, if not, I am sure it can be fixed, I just dont have the energy to put into it.
Asking price 150 euros.
The 68060 is the "good one" with mask 71E41J I beleive its the one that can be clocked to 80 mhz.
