I like the Beseler dichro 45 computerized color head that can display the precise filtration. I had one but it broke later on. I got the CB-7 and the big dichro DG head. It has bright 2 200W lamps but no actual filter readout. I got a Sargent Welch/Minolta color translator (basically a color analyzer) and connect a fiber optic cable that pipe light from the color head to its probe and works to display the actual filtration. Works great.
When I bought my DSLR my wife made me got rid of it so I sold everything there for only $200.
