"He who marches out of step hears another drum." ~ Ken Kesey
Zero problems with our Starlight. Have had it for over 6 years. We do not use the vacuum, use a CTS. Results may be different with film and vacuum, but it's super fast exposing.
Used M&R MSP 3140 exposure units (and most any single point metal halide units) are going for next to nothing these days. If you are still on film these are fantastic units and you can dial in your exposure and lock it in with the built in integrator.
