Yes, he won the 1991 pga championship with ping clubs, I am not sure if they were the isi's or the eye 2
If you are referring to the early radical shape of Ping clubs unfortunately there are very few clubs which are styled in this way no, they all now have a similar uniform shape. If you are referring to current range of Ping clubs you would be looking at something like Ping i10 or G10 or Rapture v2. You can still buy older Ping clubs as they are well known for holding their quality, playing ability and value.
Ping clubs usually hold their value very well but they are quite old. Try eBay or a pro shop see what you can get.

Ping Eye 2 irons may be the best irons Ping or anyone else ever made. Mark Calcavecchia won in Montreal, June 24, 2012, using Eye 2's. Holed a lob wedge on the 16th. TV announcers said Calc was even more consistent than Mickelson with the L wedge.
