elitewheels yea in their aliX shop they have one cheaper heavy rim brake wheelset and one more expensive lighter wheelset in like 40 and 50mm. Both 28mm external width, if you can't fit 28mm tires and wheels there are more options for 25mm width wheels on aliX. That's probably the only source of good value rim brake wheels to be found anywhere, there are a few better options but also a lot more expensive. Not much rim brake stuff around anymore generally speaking and most of what is still around is very old designs. 
I don't think there's any good option to be had outside of china period
