I suspect that vendors are going to start offering these shortly as 1 ea purchases, and probably offer a better warranty.  I would hold on for a short while as Inno starts to ship these in volume.

I started this thread as a pre-order group buy.  If someone here wants to lead a group buy now please feel free to coordinate the folks here that want to get in on the fun!  I will wait to see how my pre-buy units perform when they get here before I will be adding more.
