thats a good point.
one other piece of advice, dont bother with artwork on your control panel. There are a few people who are just so awesome that they got their control panel perfect on the first try, but if you ask around, i'm sure there are a large number of use who made panel, used it for a while, found things we didn't like, and then made another one. sometimes layouts look good on a pc screen or on paper, but once you have all of the controls mounted, the buttons just arent exactly where you would like them, or something just isn't positioned quite right. if you spend the money on artwork and then have to change stuff, you are going to have to spend that money all over again down the road. keep it plain and simple, use it for a month or so, then tweak it if necessary, then when you are happy, go for the artwork. (or don't, i like to just paint the back of the plexi glass for a very plain look)
