Steve,
Having been right where you are a few years ago, I have a few thoughts that will hopefully be helpful.
1. Check additional clubs in your neck of the woods to see if they have any members selling lathes. Let folks know you're looking--when I did this, I got half a dozen responses from people who had been thinking about selling a lathe, but hadn't gotten around to listing yet.
2. I could do 90% of the turning I do on a 12" lathe. If you already know what kinds of things you'll be turning, you will know if 12" will be enough.
3. If you want a large, new lathe, you can get a lot of lathe for the buck, not the Perfect Lathe, but a lot of lathe, in the Nova 1624, often on sale, including reconditioned at the Teknatools USA web site or Woodcraft. (+/- $1200)
Great idea to get involved with the local club.
