Short list of rim/wheel manufacturers you can't go wrong with (not exhaustive, just ones the come to mind):
- Lightbicycle
- Farsports
- Elite Wheels
- Winspace (who also make frames)
- BTLOS
How to purchase, in order of preference:
1) Direct from the companies website is best for service and support
2) Off their AliX storefront would be second - sometimes you can asave a few bucks buying from here
3) 3rd party resellers on AliX - sometimes you can save a bit more, but support will be nonexistent and you might get unlucky with a shady vendor
Bonus method: buy factory direct from manufacturer or on Alibaba. You'll get the best price, but you'll probably need to buy at least 5 sets (which you can share with your new friends on Chinertown
)
