The cost of the diodes and associated circuitry is more than a cheap 
relay. And they are susceptible to damage from lightning-created transients.

I had an Alpha 86 with pin-diode switching that worked great. Never any 
problems. But a lot of Alpha users did have problems and at some point 
they started using vacuum relays. Someone who can afford a newer Alpha 
can tell us if they still do!
