If you are going to use the Apex stand, I suggest using the larger support bars for the bottom board. This way you can pull the G70 - or whichever keyboard - out a few inches to minimize to screen blocking (which can be a problem).
Lining up the C's sounds like a good idea, but I've found that it's not really necessary. We seem to get accustomed to key placement easily and lining them up when they're so far apart doesn't do anything but satisfy the OCD in me.
Also, for anyone using this stand, put the keyboard you use/need less on the bottom, specifically because of that screen block and button problem.
hey Fran, let me know when you want to sell the 3000...
