With some luck you might also be able to find an Agilent MSO6000 within your budget.
If one (MSO6000/DSO6000) is available for 1000 euro then it would probably be the best option by far.
It's hard to believe, to get a working MSO6000 for 1000 bucks.
If someone want to sell me his device, please send PM.
At work, we bought a MSOX3034T for ~5000 EURO or ~5500 US$ (used demo device).
Which used scope will you recommend?
...There's the Agilent 54622D but that's a 2ch MSO (and does UART/SPI/CAN), but I personally would take it over a Rigol any day. They often go for <$300 or so which means there would be room for some decent probes or other gear in your budget.
Is the 54622D much different to the 54645D? Maybe I could get one...
Didn't know these old scopes had any decoding ability...

Sorry a bit late to the party on this thread, but I didn't see this addressed.
54622D and 5464
2D are 2+16 MSOs with CRTs and are both awesome scopes, I have both, but they don't do serial decode. They will do serial triggering, including basic CAN SOF triggering. The 54622D also goes into equivalent time at faster sweeps as it's quite a low 200MHz sampling rate. The 54642D is much better from this perspective at 2GSa/s and is 500MHz bandwidth. Both have reasonable memory depth too. The UI is superb in terms of ease of use and quick response, and is still the basis for Keysight's low to mid range scopes to this day.
I also have the MSO1074Z-S, which is my field scope (i.e., it's a tiny lightweight package, full of features, and if it gets lost or damaged in an aircraft hold it's not going to break the bank). For the money it's difficult to fault in any way. Sure there are some minor annoyances but I'll very happily accept its compromises for the value it provides.
You'll often find a lot of proponents for separate USB PC based LAs instead of an MSO. For many of the lower cost units, for lower speed stuff then they can be useful, I have a selection, but even then 99 times out of 100 I prefer to use an MSO, although I know others think otherwise. Typically the benefit of an MSO is its triggering ability. On the other hand some LAs offer a post processing mode instead to search for scenarios after the event. My own workflow prefers being able to adjust the triggers rather than analyse enormous captures, but it also depends on the situation.
If you can get a second hand 4ch MSO6000 for a grand it's a no brainer. My daily driver is an MSO7000 which is pretty much identical electronically to a 6000 but with a bigger telly.
