Tube tester...anyone own their own?


Since a lot of us utilize tube based gear, I am wondering how many of us own a tube tester? I am considering acquiring one, not sure if I would look for a Hickok or another brand/type.
if you are considering a tube tester, or already own one, do tell us your recommendations and your experience with the particular type you own.

A local dealer uses the Orange to do quick screens of small signal tubes and EL84 output tubes.  It is much easier to use than the TV-7 that is the main tube tester in the shop.
I use a Sencore's grid leakage test to find tubes that otherwise test fine for emissions including fine on Hickok testers. Let warm sufficiently for 15 minutes or so before test...i used to also have tubes that tested fine in my arc preamp, but were clearly not so...the sencore now catches those tubes.
If you need to have work done I would recommend Bud Allen without hesitation. You should do some research on former clients of Roger at Alltubetesters before sending him anything!

I have: Hickok 539C, Cardmatic, Heath TT-1, Maxi-Matcher (power tubes) and my favorite is my Triplett 3444. 


I have checked out a few tube testers, but so far none can test the KT150 tube....which needs a 600 volt+ test. Anyone have any recommendations?
