rebreathers- anybody out there looking at them?

[scubert]

I know there are a bunch of guys from MN up at wazee using rebreathers fairly regularly. I was doing some looking online and found several that looked interesting and somewhat, kinda, a bit, affordable (I know the words affordable and rebreather are rarely used in the same sentence, thought I'd give it a try)
the Frog and the KISS both look interesting, and relatively small and easy. I know the Meg/minimeg, CIS, Inspiration, are all out there as well as the lower end draeger stuff. Has anybody around here used any of the above (especially the frog or KISS)?

It's not like I'm looking to drop a few extra grand, I was looking at the costs of setting up another set of twins and thinking that if I could sell my first set, NOT buy the second, skip most of the regs and stage bottles used for deco diving, I could CONCEIVABLY be close to the cost of a lower end CCR.
