Mopar Madness rear axles??

Anyone ever deal with the folks at Mopar Madness. Their 8 3/4" axle packages seem pretty decently priced and well described, too.
I'm pretty ignorant about the axles, all I know is what I've read - magazine articles and such. So, any Mopar Madness customers out there wanna sound off??
Or any other makers of 8 3/4" axle assemblies, for that matter, I'm shopping....
