What are y’all using for column mounted tachs?

I’m a fan of “Day 2” modifications and I found a vintage SST-70 tach on eBay I’d like to use. These use a separate transmitter box believe. There’s some on eBay also and they’re sold as untested.

There’s a guy online “Tach Man” that refurbishes the transmitters.. assuming buying a used one is a dud. They also run off a AA sized battery that seems to be not accessible anymore

Just wondering if it’s worth all of the hassle. While some people like the dog dish sized tachometers, I’m more of a fan of the smaller vintage or at least vintage looking ones.

I may just get a new Bosch Super Tach and call it a day. This won’t be a race car but again, I love the “day 2” mods. The cool parts that were the ones to have back in the day.
