I've been using O'scopes for 40 years and have bought a
few used ones. I've come to the conclusion that expensive
ones like Tektronix, HP etc. are to be avoided. I also do
not recommend any digital scopes as they have not reached the point of being
able to replace analog scopes in all applications. I worked as the mastering
engineer at a
CD plant for over 13 years. Every month or so Tek and HP salesmen would
offer to leave me their "newest" models so that I could tell them what was
wrong with their
algorithms.  I almost never took them up. I showed them that their 20K$ plus
machines could not match a
$400 analog when it comes to real world information
about freq. below 20 Mcps. especially when viewing
complex bursts of mulitfreq. energy. Sounds like the
output of a TC.  I noticed that all the big scope companies
have quietly re-introduced an analog model or two recently. Seems they may
have realized the truth of physics.

good luck,

allan
