What country?
There are many choices at that price range.
- Rohde & Schwarz RTM3K-COM4 Promotion 1GHz RTM3000 series fully loaded- decent choice of active probes, but no used ones..
- LeCroy might have interesting stuff - very good choice of active probes old and new. They are very compatible , old ones mostly work even on new scopes.
- MSO8000 is very new. Looks like capable platform, but very expensive for what it is right now. - limited active probes at this point, no used market
- SDS5000X is interesting, very good price, so far good progress on development - limited active probes at this point, no used market
- Keysight MSOX3000T series + additional Picoscope and/or logic analyser..
Basically, if you want to decode a lot, do that on PC based analyser. Decoding thousands of packets on a scope is no fun. That's a job for keyboard, 24" + monitors and a mouse. Decoding on a scope is done for interactive checks, and as a convenience thing, everything is already connected an you check analog and digital at the same time. Also on MSO you can check for digital/analog synchronisation, to see signals together on same timescale.
