I happened across an HP 16ch logic analyzer, along with an HP freq synthesizer. Both nice pieces of equipment, but the logic analyzer didn't have the probes. Yeah, they are kind of pricey, but I also got a mainframe logic analyzer in the deal, and was able to pull the probes from it to make the standalone work. Those 3 pieces cost me $200 US. I scrapped the mainframe unit.
Still, an analog scope can still be handy for viewing transition periods, which a logic probe wouldn't see.
