Hi The whole counter thing has been run around in a thread back a month to three months ago. It's in the archives.
Bottom line - if you want a cool one, it's got parts in it that are tough to work with in a basement setting. If you stick with easy to solder parts, it's not as cheap / fast / cool. For reasonable performance, price gets above that of a "who knows if it works" 5370 on the auction sites. Even the 53181 it's self can be had fairly cheap if you spend a while (months) shopping for one. The last 53181 I bought was under $500.

I think that someone needs to take up the flag to begin a group project to scratch design a home buildable reciprocal counter. The project would teach a lot and would result in quite a few folks on this site acquiring significantly improved counting performance. Something on the order of a 53181A would be very nice. The finished module would be made of a processor, an FPGA, and some peripheral bits. The manual for the 5345A exposes quite a bit of theory and some this circuitry might be directly adaptable to an FPGA. I have been watching Scottys Spectrum Analyzer Group for years and this SA / VGA is becoming an amazing piece of equipment based on small (or not so small) contributions of many of the participants.
