Josh,
At one time, perhaps up until about 10 years ago, about the golden age for buyers at internet auctions, for a lower price, this would be the start of a nice lab setup. However, today, you can take that $2900 and put together a very capable, very nice lab setup that will have exactly what you want in it, and will take up much no more space than you need.
I do love those Tek mainframe scopes--they are superbly engineered. They are also obsolete. I have two, and keep them in running condition, only out of love. They take up too much space, and I never use them. For those who argue that analog scopes are somehow less tricky or reveal more information than digital scopes, I would say that if you don't know how to look at the signal on a digital scope, then you probably aren't fit to interpret one on an analog scope either.
I say don't do it.
