Internal mixing resin spray gun

[Basketcase]

Does anyone use one of these? I've poked around online and they seem like a great addition to the toolbox of anyone doing boat work. I'm not talking about the ones with a chopper gun built in, but just a spray gun that sprays resin and MEKP and mixes as you spray. Seems like this would save wasted resin and just speed up the process overall.

If I can find one for a good price, I may try one. I've been fiberlassing with buckets and sticks for 15 years and I've seen more than one bucket with an inch of extra resin in it. I've also had a hell of a time keeping up with mixing resin on larger layups. Seems like this would solve both problems.

Thoughts?
