[SML] dmx projector shutter

[Jeff Forbes]

Hi all.
My ProDowser seems to be giving up the ghost on me so I’m shopping around for a new one. Bakerwood the company that made the ProDowser has shut down but that is type of thing I’m looking for. The City Theatrical version is a bit too pricey for my needs, but I found this one from a company called Jerry’s Electronics.
Any one have any experience with one of these?
