I have used Contax RX, AX, RTS, RTSII and Yashica FX-3. Also have used Nikon FM2, FE2, N70, F3 and F2. By far the best built by my own subjective use are the RTSII and F2. Though none are anything I'd call slouches. I stick by my recommendation of the RTSII and 50/1.7 Planar. Probably be less than $300 total for both. Great kit.
