I'm 99% sure that web page is wrong. I don't think the 707s are Res-O-Lites. They are "standard" Gotohs but not Res-O-Lites. They're lighter than, say, stock Fender tuners, but heavier than Res-O-Lites. Someone tell me if I'm wrong but I don't think I am. Res-O-Lites have "Res-O-Lite" stamped on the back cover plate.
I've recently bought Hipshot HB6Y Ultralights in 3/8" and 1/2" sizes, and was very disappointed. They're sloppy, not smooth. I had to return one of the sets to Hipshot for replacements, which were much better but still not as smooth and precise as the Gotohs I've tried (GB704 I think, and GB350 Res-O-Lites).
Try finding Gotoh Res-O-Lites in Cosmo Black. Ishibashi will special order them. For nearly $200. Ouch!
