I am the original owner of this bppc.
the seller is trustworthy, just selling it to fund another project. The 060 is a real 60mhz one, it is a rev2 bppc and works PERFECT with bvision/g-rex. It is made by DCE, and is actually very well made, a quality product. Also the 060 is on a socket, so you could easily put the 66mhz one you have (guessing from your sig)
A very nice card, only sold it because I moved to 4000-csppc...
