Recommendations for a vacum tube tester

Maxi Matcher is what I would buy if I needed precise readings.  Only downside is you really need power and preamp capability you need two machines.  
 

I bought the Amplitrex AT1000, which admittedly is fairly expensive and is not very fast, but it is fairly powerful. This is obviously way out of the OP's price range, but for others that might be looking for a high-end unit, this is worth a look. 

Ok I just got sucked down this rabbit hole even though I was in the camp “I don’t need a tube tester”.   Won on an offer a Hickok 600A in very good working condition per seller and pics.  It was calibrated in 2022.  Cost me $250 + tax shipped to my door.  Only issue reported is a stuck settings scroll which is no big deal.  A printed list will work just fine instead.  Pretty nice testing unit feature wise at a price that can’t do much damage if I decide to resell.   Certainly not a nice Amplitrex AT1000.

@calieng thanks for the link to the maximatcher are you aware of an inexpensive, possibly usb based, small signal tube tester?

@scottya118 

Are you technically capable of building one?

I have schematic, PCB & CAD layout. PM if interested.
