Garth - You can make your own pretty cheap. Northern Tool has vacuum gauges for $5.99 ea. Ace Hardware sells needle valves that work great for damping for about $4 ea. $5 for vacuum hose and $2 for some 1/4" copper tubing for the valves and you've got yourself a decent four-carb synch gauge for about $50. The Mikes XS look like good gauges, but you only get 2.
First step is to put all the gauges on the same cylinder at the same RPM to obtain a benchmark reading. I did this with a set of pressure/vacuum gauges from Harbor Freight. They just happen to read .5" off each other at 1000 rpms. I just labeled them appropriately and take the difference into account when I synch. They work great.
I like John's idea too. Only problem I can see with a one gauge setup is you'd have to watch your RPM's very closely while you're synching as the vacuum fluctuates by rpm. Still, that sounds like the most cost-effective solution.
