I still work with an old Lecroy 9354L from time to time.
Its certainly no useless or "shit", the more advanced functions are somewhat non-intuitive to use but at least THEY WORK. And there are a LOT of these that will come in handy from time to time.
2M/ch certainly isnt bad, nor is the ability to use math over the full memory, and quite deep FFT (iirc 1M or so, gets fairly slow but it does work properly). Advanced trigger modes work fine too, reducing the need for stupid "manual glitch detection" with ultra-high wfm/sec.
Also i didnt have that thing crash or find a problematic bug yet, as opposed to pretty much any low-end scope (or anything made by Tek no matter how expensive) i ever had the displeasure to work with.
Try to find one with a CPU3 card as these are a lot faster (48Mhz 68030 vs. 16Mhz 68020) and can run newer FW with more features (upgradable via floppy drive on these, older ones are EPROM).
Stuff is quite repairable too, you get a full service manual for it and most of the "common" problems are fixable. No "leaking SMT capacitors killing the entire board" or "unobtainium hybrids failing like flies" type of fail as with some other scopes of that time. Floppy drive breaks often, but its replacable with a common laptop floppy drive for <5bucks.
So yeah, the better models from the 93xx series probably are worth more than a DS1054.
Things to stay away from:
Most TDSxxx (short memory,slow, many are terribly unreliable, close to unrepairable)
TDS1xxx, TDS2xxx (short memory, nothing but extremely basic festures)
All Tek if its broken, no service manuals for almost all of them
large-case HP greenscreens with that single encoder wheel (too old, unuseable UI)
Lecroy 7200 (wayyy to old and HUGE)
Lecroy 9400 (too old, too little features)
Most analog/digital combiscopes (too little memory, too limited features, except for some newer hamgs that are quite decent)
