16 A4000's!!!!!.... Why!?
There tons of people dying to have an A4000. Spread the wealth! (and make a little money while you're at it). I have to say, I hate it when I see people mentioning stuff like... "yah, I have an A4000, CSPPC603/060, PicassoIV... blah blah blah... sitting in my closet collecting dust because I only rarely use my A4000T, CSPPC604/060, Mediator, etc. anyway)
Some people would give anything to have some of these "dust collectors." It's fine have more than one machine if you're using them, but if you're not using them give (or sell) them to someone who would.
Sorry to get down on you, maybe you are planning on selling all those spare systems (which would be great). But still, I think there is a definate problem in this community with people hording equipment (which is probably why demand and COST is so ridiculously high).
