I wish I could order 1 U3 instead of 20 alonght with an R1.. 
.. I'll pay for shipping.
Still think they should make a U4 with the new chips.. I need another small miner. S7 is just too much for me for hobby mining.

Look over in group buy's. There are sellers such as crazy guy. He sells them 1 at a time.
He is a very good seller. There might be others but there are many ways to get 1 instead of that 20 order quantity.
