ZXR750 rearsets

I've been looking for a set of rearsets for my '92 ZXR750 and all I can find are the following (and yes I have also been looking under ZX7R
). Both the Spiegler and ProTek are non adjustable, any great need to be adjustable??
I looked under all the main manufacturers: Gilles, Sato, Vortex, PP Tuning, Woodcraft, Yoshimura, Graves, Attack, Valter Moto, Rizoma, LLS, Yanashiki, Robby Moto, Tech G and even our good friends Kaneg
Here's a link to some good info on rearsets, levers, rims etc http://www.perthstreetbikes.com/forum/mods-being-technamikle-product-reviews/
Spiegler for about $600 (bit chunky looking
)
Protek for about $420
Wet 4 U also claim to make an adjustable set that fit for $495, although they are not on their website (they wouldn't me a different model that would need persuading to fit, would they
)
Does anybody know of any other manufacturers ore retailers that stock them, or does anybody know of any for sale.
Is there anyother models that would fit without any major modifications, surely there have be more available than I have found
