Hi guys, I must admit I am kind of obsessed with good scopes...
I came here to see if anyone can share some other models that I'm not familiar with, like Agilent/Keysight, R&D, Siglent(I don't really like), RIGOL(I don't like either), YOKOGAWA etc...

The new 12-bit Rigols/Siglents are far better than anything you'll find second hand for the same price.
Hi guys, I must admit I am kind of obsessed with good scopes... So please try to focus less on the actual need (I'm working below 100MHz so a TDS220 should be enough in that case, but I just want as much performance as possible as long as the price is acceptable)
I would like to have an affordable used scope, with relatively good performance and endurance. I've done some digging and got this list:
> TDS3000B series, or more precisely TDS3014B, with easy upgrade through ethernet.
> Lecroy wavesurfer 44Xs (or similar), would also like to upgrade sample rate but just don't know how (I've seen someone succeeded).
> TDS784D/794D, just like its color CRT...
But I also have concerns about each one above:
> TDS3000 series have shallow memory depth and crazy-low waveform refresh rate, but their price are around $500 in where I am.
> I love Lecroy's enclosure size and Windows OS, wfm refresh rate is high, but expensive (around $1500, old 7300A are cheaper, but so heavy).
> CRT attracts me, memory depth and wfm refresh are fair, but too heavy, and only 1GS/s when all channels on, etc...
Hi guys, I must admit I am kind of obsessed with good scopes...You and me both.QuoteI came here to see if anyone can share some other models that I'm not familiar with, like Agilent/Keysight, R&D, Siglent(I don't really like), RIGOL(I don't like either), YOKOGAWA etc...Please tell why ?

I am not sure where the "crazy-low waveform refresh rate" comes from. The specifications list 400 waveforms per second in normal mode and 3,600 in fast trigger mode.
Re 'LeCroy': I also was attracted but recently I learned that, at least as a private or small customer you are unlikely to get support but rather a cactus in your rear from them.
Also note that to some degree Siglent can be seen as LeCroy-ish that is they produce some hardware for them and also seem to have a similar approach.
dont buy "old" used scopes if you just want to use them.
i am in the prcess of replacing around 80 capacitors in a scope made in 1996
26 of them are SMD and ALL have leaked!
@nathan as a good resume,
as an hobbyist at home
i tried some old fluke 100Mhz portable scope .... works but ...
tried the new cheap Hantek 2d15 model. was ok but basic ...
i work with old turd like TEK 7404 and 7254b, yeah yeah Windowish platforms, if they are well maintained they work, until an hard drive crash or the famous dallas clock dies, if you did not saved the power pc settings it may take a while to restart them
work with 2s Siglent sds 1000x, hacked to 200mhz simple and fun to use
work with a Rigol, hacked too to 200mhz works fine but like the Siglent a little more, but with scripting / python .. Siglent is way better
work too with a Picoscope 3406d, practical to say the least, but man very very expensive 3400$ CAD outch
wanted a used Lecroy 1 - 2 ghz models, but as mentioned, you're almost out of luck if it break, some good threads here ... unless you find a clean one and self test passed at a good price ??
oldies like tds 5k or 6k mmmm you have to see all the spc tests etc ... before even buying one, same for 7 k series, but 7k series are biiiiiiig heavyyyyyy bulkyyyyyy
we have evaluated the new Siglent SDS 7k series, my boss is hesitating ... but man this scope was NIX based and runned darn well for the tests we needed / done. having 27k$$ CAD i would have bought it right away loll
Agilent mmmmmm not, now they don't deal with single individual ... not new for sure, maybe some Infinium series
in the end good ol scope depends of your need, but if you compare modern things with the oldies ... you'll be deceived in some ways, you have to know your needs for sure, and know how to deal with them if they break ??
my 2 cents
still some good ol series of tek tds 7xx series up to 1 gig, you can do some BW upgrades ...
tds3k serie, way overpriced for what they offer, but BW upgradeable too
and now the race between Rigol and Siglent give us more for the money ... with easy BW upgrades cough cough loll same for many items, sig gens etc ...
