Wow Alan - that's a seriously geeky spreadsheet! But I was just about to do something similar, so nice one!
You don't have the width for the DMM 3cu's in there... as they're going at about half the price of the X4s and Totem's, it would be interesting to know if they would fit the bill? I know they are supposed to be a fair bit narrower.
I guess they are being discontinued in anticipation of the DMM micro cams that another poster has suggested they are developing?
