Sixgun Nut
I'd start with Gunbroker. Here's a Turnbull model just like the one from TenRing for $200 less. There's also a nice flat-top target on there.

An earlier USPFA (Uberti parts fitted and finished in Hartford, name changed to USFA in 1997) for quite a bit less but it has a cylinder ring from mishandling.
