Polo Wheels (Tyres, Spokes & Rims)

Can someone please recommend a 36h front disc brake wheel, for 700 / 29 ?
An off the peg one, doesnt have to be any of your fancy components, just standard.
One that has a shimano centre lock rotor mount rather than the iso 6 bolts.

My google-fu seems to have left me today.

Shimano MT55

£80 for QR front

Anyone know of a decent 32h 26" rim? Welded instead of pinned. Doesn't have to be eyleted but I'd prefer it.

XC717 or XC717Disc.
