Dan,
If any of those expensive things are FPGA, like the one used in the Roach2,
XC6VSX475T-2FFG1759C, we have been supplying these at a discounted price
from Digikey's.

Subject: warning about Tenma dc power supplies
we've had an epidemic of failing Tenma dc supplies that fail to maximum
voltage (shorted pass transistor), and have blown out expensive stuff in
some research labs here
fwiw, they are models 72-6905 and 72-6615; they are (i think) linear
supplies
maybe best to avoid these things altogether
