The one I used is made by Moflon, three wires, 30Amp and cost me about $30. MW1330 is the model I have. As always your mileage will vary.
If you are after just doing control signals, Adafruit has some low voltage, low current ones. 2A / 6 wires ~$15 plus shipping.

I've got one similar to your 30A one. The big issue is that means I'd have to run CIMs on a 30A breaker since the slip ring is only rated to 30A. It's for 16 style swerve modules. And getting rid of the extra wire would help them be lighter.
