I've been window shopping the self-deploying 360 recently. I'm not completely sold on them so I would be looking for a used one to save money. Are there different versions of them or are they all the same technology? I've seen some used units around for sale that are around two years old. I recently purchased new mega gen 2 units about four months ago that I would use it on. One deterrence I have is that fact that I'll have to spend another $250 just to network it all together. Currently I don't have to use a network since my 10"di and 12"si are hooked directly together.
