That’s a good tester for preventing your gear from becoming a “tube tester”.   Mine saved me from putting a bad rectifier in a new amp.    It was worth the money to me.   
 

Mine is similar to that, it’s an 800.   It is super easy to use and does everything I need it to.   All of my gear is tubed so it does get regular use.   

Hi Dill, For myself.

B&K make good basic used testers in your price range. Several models to consider are: 550, 607, 667, 700, 707. It most likely will need to be calibrated.
