I was in the same predicament when a student. They said they’d give me my pick of scope if I went through a checked out the other 20 that were to be sold. 30 years later I still have that 20 MHz Tek scope.
And with proper care and feeding, that Tek 20 MHz scope will be working in another 30 years. They were well built to put it mildly. I have a friend who's scope is a Tek 500 series, I think 30MHz, built around 50 years ago. Works fine once it warms up. He uses it for audio work, so 30Mhz is mostly overkill.
