I want to put slicks on my bike since lately I've been using it more as a commuter. I will occasionally hit the trails(on the weekends) and I've decided that instead of swapping out tires once a week, I'd rather have a pair of extra wheels, which would make it much easier for me.

I have an entry-level bike, which is fine for my uses, but I need some help on what kind and where to buy a decent wheelset that doesn't cost more than my bike did. Is there a decent wheelset that can be had for less than $100? I don't need anything spectacular, as the wheelset I have now, is nothing spectacular and works just fine for me. I just need something that is durable and affordable.

Does anyone have any ideas?
