I am with stewart0722 above. I own the Prime with Ortofon Cadenza Black with the Phoenix engineering system and upgraded (HRX I think?) record clamp, double pulley. Sounds really great and with the 3D arm it is hard to beat. You don't have to go crazy with the cartridge but a good one makes a huge difference.
Now I also own a nicely, but not fully restored TD-124 with SME 3009 arm which was rewired. It has a Denon 103 and a nice plinth - all in equals the price of the Ortofon (which I got with a very significant discount). Comparing the two tables from this perspective I would say that the TD-124 (MK-I) stands the test of time.
