[DeTomaso] Recommendations for Cordless (i.e., rechargeable) Ratchets?

[Ken Green]

I've seen several cordless ratchets made by Ingersoll Rand, ZNEX (who are they), and others.  Does anyone have a recommendation?  Does anyone have the much less expensive skill ratchet?
 
I'm in the process of mounting and removing parts to mock up things, and it would be a lot easier to use an electric ratchet and a pneumatic.
 
Thanks,
 
Ken
