One good tube tester make is Triplet, I don't know if they made Mutual Conductance models but they are well made and will tell you whether a tube is stuffed or no. I'm never actually seen a Weston tube tester but know that they had a good reputation in the analog volt-ohm meter market for years, if there was a Heathkit clone of a Weston it's probably a decent tube tester.
Most of us that play with a range of radios from different eras usually need at least two tube testers to cover the range of tube bases over the years. A tester that will test 001As and #45s will not usually test duodecal TV tubes from the 1960s. If you need to test foreign based tubes then all bets are off, I'm fortunate to have a RCAF spec military tube tester that covers some of them because the Canadian Military used to buy a lot of British crap, except for Phillips side contact bases.
