I went though a series of digital scopes before I found one I was really happy with. All were second-hand.
I had a 16500A, later upgraded to a 16500B. I didn't ever get the LAN option. On the positive side, it's a proper logic analyser with loads of inputs, clock and state triggering : the mixed-signal scopes don't usually have enough inputs to deal with an Z80/68000 era bus. But the scope part is 400MS/s, 6 bits and a bit clunky. The whole thing is huge and noisy. I bought a cheap Owon with a TN screen. It was awful. Got rid of it. I bought an early Rigol. Didn't like the very small screen. Sold it. I bought an Agilent DSO7014A then upgraded it for free to MSO7054A spec (mixed signal, 500MHz, 4GS/s). It's great and even though it's obsolete now I will be using it for a long time. The 5000 and 6000 series are similar (see reviews by Mike's Electric Stuff) and can have a VGA screen attached for a larger display. I also have a Hantek similar to the one Richard describes ut an MSO. It's not in the class of the Agilent as you might expect at 1/10 the price, and the digital inputs in particular are poor (no trigger) but it's useful as a portable. My feeling is that of the chinese scopes, Siglent and Rigol are the best of the bunch but I'm going mostly on hearsay - the one I owned is not representative of current models. I think it's worth making cheap mistakes to learn what you want, and worth spending a lot more if you use a scope every day as I do. And it took me 6 months to properly shift to using the Agilent from an analog Tek so do be patient and don't assume it will be instantly familiar if you have a long history with analog scopes. The earliest ones in this list really just added one-off waveform capture. But the Agilent tries hard to be 'as good' as an analog scope along with all the digital bells and whistles. It's not an easy thing to do but there's a reason the frontrunners eventually stopped making analog scopes at all. However, the early ones don't match up so although I didn't buy new, I did learn what would be disappointing and used only as an alternative.
