It's easy to burn dollars in connectors, an enclosure, and a circuit 
board that matches the relays you have, all in addition to the relays 
themselves. Layout is also non-trivial if you want decent RF performance 
-- the entire path must be a transmission line, so the return path must 
run on a layer directly under the switched path. The Top Ten 6x1 goes 
for $125, so if it's any good, it's worth it.

Thanks for the offer of parts, Don.  I could make good use of some high 
power (1.5kW on HF) coax relays with 12-28V coils for other parts of 
what I'm doing.

Have a good trip!
