Hi Linna,
I too would be very interested to buy one at least, maybe five of the effects mechanism including the wheels, motors and mounts plus the DMX board to experiment with. I am sure there are a number of people on PL who would also be interested. The number of units I would buy would depend upon the power rating of the gratings. At the worst case can you supply the projector without the lasers? If so how much would this be? One final question is if I buy just one projector to experiment, as you suggest, is the shipping still free? I live in the UK.
Kind Regards
Steve
