Anyone Here Ever Purchased A Tube Tester?

I frequently blab about everyone who has tube equipment getting an inexpensive tube tester.

I bought this Accurate Model 257 for a friend.

It's results matched the results of my smaller model 157. My Model 157 always matched my big heavy Jackson, so I gave the Jackson to a friend who used to bring his tubes here.

I had one briefly that had three more knobs than the space station cockpit. I sold it to somebody hopefully smarter and more committed than me, which would not have been hard..,

When I started playing with 4 pin DHT and rectifiers I bought a Hickok 800.   It looks like it should be in a museum, it's that nice.  It was serviced not too long ago and have saved me from using a bad tubemore that once.  It paid for itself by not allowing tubes to damage my gear.   

I use a cheap vintage tester, Superior TD65 purchased on eBay and it gives me what I need to know and works fine. I highly suggest anyone with tube gear get one. It doesn’t have to be a very expensive one, but one that will tell you if a tube is bad, weak, or not.
