I think it may depend on which tube components you own and how many tubes.
If you have a preamp/line stage which doesn't stress tubes or possibly a D/A converter or other component with on 1-2 tubes then sending them off to be checked should not be a frequent task. But with an amplifier or anything with several tubes it should be more convenient having your own tester.
I understand that Hickoks are frequently recommended but there are others, and usually for less money. I've had a B&K 707 for several years which served me well. Also kit companies such as Heath, as well as Eico, sold lots of testers.
If you decide to buy one I'll offer two suggestions. Be certain the tube charts are included, otherwise they may be difficult to locate. And having instructions to calibrate the unit would be important, just consider how old nearly all of these units are now.
