A carbon fibre driveshaft weaved from dry, high modulus fibre is technically superior to one that is made with layers of wet carbon fibre sheets.
Velox used to make one with dry fibre, but there wasn't sufficient demand and no more.
A Taiwanese factory still makes one weaved from dry fibre:

Retail price is US$1,200 plus shipping (about US$50 to USA). But this is a factory and you need to contact the factory yourself.
