Okay I have finally jumped in on this and have purchased 1 "Full" controller and 3 standards on the way.

I know I am way late to the game with these however from the reviews I have seen I'm pretty excited about getting these going.

Not to mention that I really love the ability to help secure the network further by adding a full node to the BTC network.

Also, incredibly optimistic that the next release will allow solo mining to the node itself.
