I don't know specifically for motor condensers, but some good reputation capacitor brands off the top of my head are:
Nichicon
Nippon Chemicon
Xicon
Rubycon
Sprague/Vishay
Cornell-Dubilier
Mallory
I've used all of these in radio repair and never had a problem so far.
Yes, you may not necessarily get "made in the USA" products since these companies have world-wide manufacturing facilities. But the Quality Control seems to be good.
