Turbo Seca question

I've only had the opportunity to work on (successfully, I might add) one turbo Seca, and afterward had the pleasure of test riding it. I was pleasantly 8O shocked when the turbo finally kicked in...
What sort of production numbers were these things produced in, and are there many left out there (reasonably priced, of course)? I've been watching the local Craigslists and haven't seen any recently.

 

1982--6500
1983--1500

These numbers are worldwide. I'd say only about a 1/4 still remain running if that, maybe another 1/3 sitting somewhere collecting dust or outside getting rusted and corroded....the rest have been wrecked, junked or fubared by an owner who did NOT know how to work on them (or rode them hard with gas in the oil and screwed over the bearings). I currently have an 82 & 83 that I ride, and another 82 & 83 sitting in the barn as someday projects. I live in Ohio and have seen a couple recently on craigslist ranging from $800 to $3000 in the quad state area. It's hard to tell how hard a life a turbo motor has had until you can hear it running (turbocharger condition too) If you do find one for yourself and it's not too thrashed you will never want to get rid of it!

 

Thanks for the reply.
I had no idea there were that few of them produced. The one I worked on was purchased by a local collector who employs his own personal mechanic. This guy was afraid of the Turbo Seca and told the owner that carb parts were "unobtanium". Chacal fixed me right up, and I had it up and running in a few weeks (This bike was featured in Cycle World last year in a Peter Egan article) and it is one sweet ride! I really didn't want to give it back, but the guy paid me & all, so....
Anyway, even though the production numbers are low, I'll keep my eyes peeled.
