FR64S is best bang for the buck. FR66 is better, but expensive to buy.
66FX I have never heard, but is lighter mass and costs less to buy than 66S. 407 has mixed reviews - most folk believe the FR64S/66 are the best built, and sounding. There have been some reports of quality issues with the Ikeda range ( not built by Ikeda, founder of FR ). The FR’s have the lateral weight balance on the side to balance the whole arm/cartridge, which was omitted on the Ikeda series arms.
One advantage with the longer arms is that you will have lower tracking error with the fixed headshell cartridges such as the EMT/SPU where you cannot alter the tracking angle.
I have had 2 FR64S with no problems.
