It's a bit pricey that but it appears to be the only one available right now. Years ago I bought an allegedly rebuilt 6 speed box with only a couple of subsequent races under its belt that quickly needed some synchro's replacing by R&RT. I did the same again last year, with a similar story, for my current car but having learned a lesson took it straight to R&RT for a cautionary check over and it needed a couple of synchro's. Even then, all in, quite a bit less than this one.
