7 year old, huh? Running V-brakes?
I've noticed that most pre-built wheels at the usual online stores are all disc-rim wheelset. Rim brake wheelsets are hard to find nowadays but not impossible. Vuelta make rim/disc rim/hub wheelset that are a decent value. I have a set on my commuter bike that's been bullet proof going on four years and it's still true. You can find a couple Vuelta wheelsets on ebay. Mavic still produce a rim-brake entry level wheelset, the CrossRide I think. I've used several Mavic wheelsets and they've been great but the proprietary wheel components could put one off.
You could go the custom route and you'll have to open your wallet a little wider but you'll get a wheel you want/need.
