yeah but the parts stores round here are afraid of ticking off the shops they supply by making it easier for folks not to go to them for simple crap, not one parts store in town will even lend a code reader
I could go on for a bit but I really am kinda bitter about it

I know Autozone doe not have diesel compression testers, don't even have the regular compression testers on the loaner program. Harbor Freight has them for around $50 or less generally. They do cover anything with a glow plug for sure.

If you already have the necessary other stuff just laying around your garage, I would get the harbour freight kit.
I just happened to have solder supplies, simple propane torch, and an old glowplug.
I took my time by cutting off the valve on the supposed adaptor for our trucks. I then cut an old glowplug accordingly and soldered things together so it would thread in without bottoming out, etc. compared to an old glowplug depth.
It worked for me, did 2 runs and got the same results. I kept the tool in the drawer for later use just in case as well.
Now as far as actual readings compared to a "professional" gage I cannot vouch for, but my one experience showed everything looked alright.

Well, mine from HF just showed up, it's a U.S. General #93644, It states in the parts list a M10x1 adapter is included, It's supposed to be adapter number 17 for the Ford/Navistar 6.9L - 7.3L up to 1994 ... I must be blind and dumb or they are!
There is an adapter that has the correct threads, however it is way to long to work.
The quick disconnect is unusual, finding adapters to fit is unlikely, however there is an 1/8" male pipe thread adapter with schrader, so adapting should be easy.
-Enjoy
