For the record, all said and done it was a $106. So definitely not a fancy distributor.
I find it hard to believe that (undoubtedly?) chinese distributors work as good as they do. I certainly have my doubts when a "cheap" pickup coil and module will run you easily $60-70, but somehow it seems they pull it off.
Not like it's often, but having a spare distributor isn't necessarily a bad thing. Fuel pump and distributor are the only things that have ever left me stranded, and the distributor is the only one that I could have swapped easily and kept going. I'm starting to become a proponent of carrying a decent amount of easily changed spare parts (distributor, plug wires, fuel pump, water pump, etc) with the older rig, especially the further away from home I get.
For that to work it takes a lot of work because that module other than 4 wires also needs the heat sink, one of the reasons why some modules burn too quickly is that people don't do it right with the white pastei have heard of setups where the owner wired up two ignition modules and elec fuel pumps (in parallel?), so that in the highly unlikely event one of them failed, you just literally flip a switch and keep going.
