The 465B was a great scope, IMO far better than the HP stuff. Remember though that this is a very elderly scope by now, and you can expect stiff controls, dirty controls, cracked plastic couplers and related molded parts. Caps can be going bad, though they did use good parts. The packaging density is very high for its time, so working on it can be difficult. It's a complicated scope in terms of circuitry. It's surprisingly heavy. If it's all that's easily available, I'd go for it, just don't pay too much and go in with your eyes open as to the potential for problems.
