Suggestions?
From your response it seems like the Owon is not a good choice and that you suggest paying more money for the sds1102x+. I was trying to spend <$500 because this is a beginner scope. If its absolutely worth it, I can stretch my budget a bit.
Am I understanding your response?
Actually I think its more accurate to say - I want to spend close to the price of the Rigol 1054Z @ $399 and will expand the budget to get a better oscilloscope especially with holiday deals.

I'm pointing out the MSO (X+) version in case you weren't aware of it.Actually I think its more accurate to say - I want to spend close to the price of the Rigol 1054Z @ $399 and will expand the budget to get a better oscilloscope especially with holiday deals.OK, you're budget constrained, just make sure the unit you buy has the Decode option for free as per the current promotion.
Siglent is real MSO. Owon is not. It is LA or analog scope. But you can not use it mixed. I have not used this Owon model but I have never seen any evidence, any signs, that it can run LA and Analog signals simultaneously. It is dual mode equipment, other mode is pure LA alone. Other mode is Oscilloscope alone. No mixed, until some one show any evidence I'm wrong. I believe Owon show even one image in they AD's where can see analog signal on the screen where is also digital LA running - if this Mixed mode is possible.
So between the SDS1102X and the X+, it seems like its just the waveform generator @ 25MHz. Is a 25MHz generator worth the extra money? I have an idea of what they do but don't know that I will need it. Right now I have an arduino, some schematics, now a logic analyzer, and some project ideas. Will I use a AWG?
After talking in the IRC channel last night, I arrived at the conclusion that I need to research a bit more and just make a call, so I am just buying both because either way I will have a scope that I can deal with.
Here are some tests on horizontal system:

Are you are pointing out that Rigol uses a smoothing function that heavily approximates actual results and that siglent's smoothing function is closer to the real sample set? Given that you are a distributor and seem to believe in siglent products I assume this is your position as well as rf-kill's initial point in the post.
I haven't read past the first page because I have to look up every concept in wikipedia and extrapolate, but am I in the right ballpark?
I am going to keep reading but want to make sure I am making progress in the right direction. Also its nice to interact with intelligent people, this is a cool forum.

Don't mock rf-loop, he's one of a few very knowledgeable members on this forum and a fellow Siglent and OWON distributor.
He's been a position to buy and test some Rigol products extensively and then post the facts here on the forum.
If you choose to ignore his findings, that's entirely your prerogative.
If you want to study more of what he has found use the Search button with a brand/model # and specify his forum name in the member box.
By all means keep asking questions.
Good luck with your swat.

sorry, im still quite new and i am trying to decipher what the test results mean. They seem to be measured in time (ns and us - nano, micro?) and then against a time base (what time is shown in capture?). Is the plot the time it takes to display a Rise / Period?
If so, then faster (less) is better?
It also seems like you are looking for an indication of which memory "zone" is used, primary or secondary. Is this similar to tiered performance memories like cpu cache? Or are you testing about the tradeoffs made when the available memory shrinks because memory is allocated in zones and as different functions of the oscilloscope use different amounts of memory, forcing the a reallocation of memory zones that has a negative effect on performance?
I am still reading through trying to understand whats you mean by 1K mem and 70K. I believe you are saying that the Rigol behaves as if it has 1K of memory while the siglent behaves as if it has 70K while they both claim much more available memory.
Maybe i'm off?
The wrong conclusion from that discussion is that only really cheap scopes use screen data; all oscilloscopes from Keysight use screen data!
