Hey Matt,

if you send me one of each, I will test them out ;)

I know the M-max when I tested it seemed to be pretty much the same as a wiresplice, jut in a neat package at a $100.00.

The HRC was nice, when inline on the HRC wiring loom, but all that together was like $200.00.

Don't know about the posh, but I have read that it's the same as the M-max when a voltmeter was put to it.
