Hello ronarthur and welcome,
I second the emotions of the previous posters, but caution that East Coast cars are generally more expensive than California ones of the same vintage and condition. Maybe as much as 2x. In particular, CA autos face emissions testing as early as 1975, so the cars must be better maintained just to be on the road. Knowing what I do now, if forced to start the process again, I would have one of our West Coast members pick a couple of candidates (see below), and fly out for inspection and negotiation; there's that much more bang for the buck.
Each series of Spiders have advantages and disadvantages vs. others; search this site and others to learn about the differences and apply this knowledge to your own likes, dislikes, dollar and time budget, mechanical ability, etc. Factor in historic vs. regular registration, inspection and insurance. Maybe go to an event or two to meet and quiz other owners.
Then all you have to do is pick a suitable vintage, price range, and (most importantly) color! You'll have all winter to search for the right car...
