I did some research for my refinish project. From what I could find, new Tight End R bridges are only available through Ibanez (your local supplier might be able to order for you). Only in cosmo black and prices seem to be in the $110-$150 range.
Ebay and Reverb prices are cheaper. Also only cosmo black. Used, new or 'fallen off a truck' I don't know. Prices around $80.
It's supposed to look like a trem, so for a hardtail it's kinda big. My hands-on experience is just 10 minutes in a store. But it did feel nice. The reactions I can find online seem to agree: it works and is comfortable. Ibanez puts these on Premium, Prestige and J. Custom guitars so it can't be rubbish.
