Signals are expensive, period. The electronics is not too bad, even though some peopel seem to think it is. A single SE8C from DIgitrax will drive 32 signal heads - 8 complete 'plants' - dual head ont he main approaching the points, single head on the main approaching the frog side, and single head ont he siding approaching the frog. As well as drive the tortoise for each fo those 8 plants, AND take input from a block detector to detec occupancy in each plant. For a street price of around $100. Tha's less than $13 of electronics per plant. It's the SIGNALS that cost - Atlas and NJ International make the Type G signals I need, and they are $29 for a single had and $34 for a dual head. EACH.
Since you use a Digitrax DCC system you'll already have the Loconet cable run to connect the SE8C - no additional wiring busses needed. The computer interface is the way to go - get a Locobuffer II or if slightly electronically inclined build one using the bare board from Hans Deloof. I built one for myself and later made one for Spacemouse. Add FREE JMRI software and you're all set. You can do a lot more than just runt he signals with that. You cna use the DecoderPro component to program your decoders, you cna bring up a throttle (or a bunch of them) ont he computer screen for additional throttles, you can monitor Loconet activity, manage the slots in the command station, manage consisting, and more.
