He can always go for the Jands Vista Grog, thats a fun one too. Budget would help, so would applaction. If its just moving light control with little
conventionals, Hog PC or Light Jockey. The lower end would be stuff like Elation's Compu Live or Chauvet's ShowXpress. This stuff is just PC control, very easy for to use for ML control. There are also a bunch of cheaper consoles out there that can control MLs, just not as easy as these PC controls.
If you need a theatric console, I'm with Grog. An
ETC Express works nicely, easy to learn, and ML control isn't very hard. Not the best for ML control, but if your in a
theatre setting with only a couple of MLs, then you can't go wrong with it. Cheaper would be Smartfade ML.
Cheaper then that, you are looking at DJ/Club/Bar stuff, not really for theatre at all. If you are just looking for something to control a couple MLs for a theatric show and can't spend the money for a Smartfade ML, I would say look at using two consoles. Your two scene preset for conventionals and and something like what JD suggested for MLs or a PC controller above. As stated again by JD, the more you spend, the easier it will be to control MLs. Also, it will be easier to included conventional fixtures as well with higher dollar ML consoles.
