I think the V9 appeals mostly to people who want to learn about mining, but don't want to invest thousands of dollars up-front. If I were just getting started, the V9 would be worth the money just so that I can make sure I know how everything works before purchasing a more efficient (expensive) miner. Besides, lots of people don't mind using these as glorified space heaters that earn a little money to offset the electricity. I have a neighbor using some D3s for that purpose specifically.

I actually broke down and ordered a 5 pack.
With the knowledge that these units are never going to make a profit I figure they are good to demo to people who want to learn about mining.
It will let them know that this is the noise level you have to deal with if you want it in your home. This is the cost to run it etc.

Also, they will run off a single 1300w power supply on 110V so I can tote it around.

Might not be the best deal, but at that price to show them around and possibly sell one or two for to people who know the score might not be the worst.
Lets face it with shipping, import duties my cost is probably going to be a bit above $450. To show it to someone and let them have it for $475 to $500 with them knowing that it's never going to turn a profit is fine by me if they want to play around with it.

I really miss the S3 :-)
