Marc..there is money to be made here..to be sure.....a system with all requirements covered is easy to pull together....have been playing with one and its not as tough as it seems. Have 2 cal labs ready to drop it into..soon as I get a bit of free time to finish it. Its generic to be sure, all it needs is the technical stuff for the specality calibrations, but the labs I plan to do are regular stuff...no fluids, pressure or gas so I am Ok.
