Well, I went ahead and bought the Genz Benz rig. I got the GBE600 head (in a nice little rack, too) with the 2 button channel selecting footswitch and the Neox212 cab.
I had it out on trial this weekend and I was able to dial in a nice sound at 3 different gigs - including an outdoor wedding reception - with no trouble at all. Should be even better after I have some time with it and really work with all the tone shapping options that are available.
I am excited to be off the rig merry-go-round. I know I have said it before, but I think with this rig, I have a really good chance of sticking to it. I have learned to work with one bass, I think I can do the same with the rig. After all, it's not like I'm settling for a piece of junk. It's a GB!
Thanks to everyone for their insight, thoughts, advice and comments.
