As people have already said, Hope Hoops are pretty much a no brainer - and if you're fairly quick, you can get 'em from Evans with 20% off (or see if your LBS will price match 'em). I've tried lots of other alternatives, Shimano, Mavic, American Classic, custom handbuilds yada yada, but the Hopes win out for the combination of quality, value, strength and reasonable weight - they're also just about the most adaptable as far as front axles go, so if you swap forks or bike, you're not stuck.
On various bikes, I'm running Hopes on DT 4.2, Stans 355's, Crests (in both 26" & 29") and until recently Flows. The Crests are a great XC/Trail rim and you'll end up with a sub 1700g wheelset. IMO, Flows are good if you're heavy-ish (95kg+) and/or regularly go off big drop offs or do a bit of light-moderate DH - otherwise they can be a bit overkill. FWIW, I ran a Hope Pro 2 & Crests wheelset on a 2010 Fuel EX and found they really suited it well - sure they took about 450-500g off weight.
