Although those are all discontinued models, it's still good stuff, and supported by the current software. On the low side, it's worth about seven or eight grand, so I'd say you got a pretty good deal :-)

The Cresnet II and MS are controllers, and you only need one. You *could* use two or three, linked together, if you want to get "tricky" or need more inputs, outputs, or program space. That would still leave you with five or six to sell, and make a few bucks :-) If you don't use all 12 touchpanels, they're also very popular on Ebay. Or, I'd consider trading programming for some of your surplus -- email me, if interested.
