I got these rims from amazon and they are great. It was somewhere around 20 for the rear and 18 for the front.
The spokes are 12 guage spokes. Standard spokes are .85 in. These are a thick .1 in. as you can see.
The rims are 1.425 inches wide which is almost 50% wider than my old mountain bike rims at 1.015.
The same tires still fit though which is great. The wheels did come a little scratched but for 20 bucks i was very impressed with the quality.
