Silver - Sapim Strongs (

Black DT Supercomp (

But if the budget will stretch, go for Sapim CX-Rays.
For looks (and strength) the Pillar Heavy Duty Aeros are great (

For colour (and if your budget will reeeeaaaalllly stretch) you could go for titanium Marwis (

Pillar also does a carbon spoke, which would make a pretty amazing looking wheel, but you might not be able to afford to eat for a few months while you pay them off. I know I couldn't afford them.
