Is the Rigol DS1054Z still the best buy for a cheap entry level oscilloscope?

That depends on your application. What do you plan to use it for?
rstofer:
Bandwidth is the most important spec, right after channels. Since the question is specific to 2 channel scopes, the new Siglent at 200 MHz is probably as good as it gets.

The thing is, 2 channels scopes are somewhat limiting when you want to do things like decode SPI transactions where you would really like to see 4 signals simultaneously. If this application is of no concern then so be it.
The Rigol is a very good 4 channel 100 MHz scope (when unlocked) at about the same price as the Siglent above. So, the decision is 4 channels/100 MHz versus 2 channels/200 MHz.
If I was willing to sink $600 in a scope, I think I would kick in a little more and get the SDS1204X-E 4 channels, 200 MHz. Remember, bandwidth is king, except channels.

One of these days I'm going to buy the sds1204x-e. I have the Rigol so there is no hurry but that Siglent is getting some rave reviews.

Under $600, by far the best value is now SDS1104X-E !
See the reason why:

Sure put the SDS1202X-E up in this discussion for a good bit less @$ 379 however it's much less featured than the 200 MHz SDS1204X-E 4ch equivalent but we don't have to spend $759 for it now. ;)
mrrrwhat:
From china, there have a special model call sds1104x-c that can free upgrade to 200M
(the cost down version of sds1104x-e)
Waveform Capture Rate (Max.) downgrade to 50,000 wfm/s (normal mode), 200,000 wfm/s (sequence mode)
sds1104x-c and ds2072a are selling same price from china, i am comparing which one better

The SDS1004X-C doesn't appear to offer MSO support either but the pics still show the S-Bus front connector. :-//
If sampling rate is what you want get the DS, but for channels, get the SDS.
