When it comes to testing, and then matching there are ways to do it that don't require you to spend that kind of coin. Find an older tube tester, suitcase type, that has a self calibration test. Or, if you are not as trusting in it, have a tech go through it and check all the connections/caps for any possible issues. Then, use it to test how strong the tube is, leaks, shorts....so you at least know what you're getting into with each tube. When it comes to matching, all you have to do is get a bias tool that attaches to your multimeter, or get one that has its own reader, and use the same amp to test all of your 34s, for example. Write the number down on the tube base. After you finish you can then match them all up yourself. 6L6? Do the same thing with a 6L6 amp you own. This is a much easier way, and cheaper than spending 2K on the Maxi Matcher. It's a great piece of gear, but that's a lot of coin on something that's not a guitar or amp. My Mighty Mite tester was 45 bucks on ebay 10 years ago, and it's never failed in telling me what tubes are good, how strong they are vs which ones are bad and might take out something in my amps.
