Steve, I would drive over and grab that Genz rig TODAY, if it were me. I have a NeoX 112 and a 212. If I could only have one cabinet it would be the 212, hands down. It can handle bigger things no problem. And it's not heavy at all. 59 pounds. It's tall, so it isn't wide and can fit into any 4 door car easily. Edle lift handles, tilt back casters, etc. It's just a great cab. The geometry of the cab keeps it from feeling big and huge like a regular diagonal 212.
The 112 to me is great, but I find I that I'm rarely using it alone unless it's for something very, very small, like a little coffee house or restaraunt thing. The 212 just sounds much better to me at equal volumes. I think it's because one of the drivers is higher, plus the larger cab size means deeper lows.
I haven't played a GBE 600 anywhere but in a store, but it was great. I have a 1200 and a Neo-pak, and I use the Neo-pak 99% of the time because it's so light and sounds fantastic. Coupled with the carrying bag, it's a cinch to move around. I put my basses in a gig bag with double shoulder straps, clip the Neo-pak bag on to that with a big carabiner, and then push the 212 wherever I need to go. One trip, easy as pie.
There is a Neo-pak on ebay right now for around $500. Supposedly only has an hour or two of use on it.
