Hell, you can buy a brand new intake cam from Nissan for 'bout $150 + shipping. And most owners like Chrissy are selling there intake and/or exhaust cams for anywhere between $75 and $100 if not less.
Looks like someone is gonna get raped on eBay.
I did buy mine new through www.NissanParts.cc for $165 shipped to my door. At the time, could not find anyone with good used ones. Maybe I paid too much, maybe not. SCC stated they were well $238 retail new when the article was written last year on the '91 intake cam swap.
