Snow no problem - I still have the studs on

I am not too bummed out with all the snow that is supposed to hit us tonight and tomorrow. I still have the studs on the mountain bike. I am thinking about purchasing another set of wheels to run with slicks for the non-snow days. I would then being able to do a quick change over to studs for snow or crappy days. I'm look to spend under $500 and want the wheels to be light as possible. Any suggestions?

Yesterday was the first day I could walk around without limping. It's been over a month now with 3 days a week visits to the bone cracker. Next week I will be down to 2 days a week and I am going to try to set it up for Wednesdays and Saturdays so I can start commuting again.
