Skip White distributor... Only "1 sold" on eBay (?)

I've been trying to learn about electronic distributors, HEI, and original points style distributors. I think I'm going to go with the Skip White HEI setup, as I've read a lot here about people running them with good results and performance. I looked on eBay, found the seller and the distributor, the ad says "more than 10 available, 1 sold" (?) am I looking at the right distributor? Here is a link [ame="http://www.ebay.com/itm/MOPAR-DODGE-CHRYSLER-318-340-360-HEI-DISTRIBUTOR-6713-R-/351108362051?pt=Motors_Car_Truck_Parts_Accessories&vxp=mtr&hash=item51bfb06f43"]Mopar Dodge Chrysler 318 340 360 Hei Distributor 6713 R | eBay[/ame]

Also, a while back somebody was going to posting a detailed installation with findings on the Skip White distributor, anybody have the link? BTW, this was for an LA engine (360) going in my Dart.
