Tony, one trick to consider is to watch for a used Garmin GTX320. It
is a solid-state unit (no cavity tube) with fairly low power draw, and
you'll often find them on the used market where someone is swapping
out for a GTX327. I got one for $800 a while back and shoehorned it
and an ACK encoder into my HP-18 panel. The whole setup cost a bit
under $1K.

Thanks, Bob K
