Superior Distributing is a major tool dealer downtown. There is a Rockler out near Castleton (you'll have to look up the addresses on the 'net), although I don't remember that Rockler had much in the way of floor tools, and certainly not lathes other than maybe one of the minis. I understand a new Woodcraft has or will open in the area. They usually have a couple of full size as well as the minis (at least the one in Casselberry {Orlando} does).
Superior is worth a visit no matter what your situation.
I'm not sure about prices, but a lot of turners I know have Jets. I think there's an older Delta in that price range, too. But then I know a lot of serious turners, and the Jet/Delta was probably four or five lathes ago for them. Don't kid yourself; you're just starting - this will not be your last lathe.
You can also frequently find old Powermatics on ebay for a reasonable price, and they are well regarded.

There is an active AAW (I think that's it; American Association of Woodturners) chapter in Indy. I have a couple of friends who are involved with it. Look 'em up on the 'net and see if you can contact some locals. They'll have great advice.
