VGA output is entirely reasonable - it's the composite that's really strange (assuming that's what that yellow phono/RCA socket is).
Owon have "previous" for terrible DMM designs. I really can't see how anyone thought it made any sense to include one in a scope like this, less so with the inputs on the back.
It's the latest craze of "5 in 1" etc feature scopes. They thought one-up other in marketing by adding an actual multimeter input instead of just a software multimeter.
Just looked up the NEC UD2-4 relay at Digikey. Twelve types. No stock. Photo shows NEC but the manufacturer is listed as Kemet.
Kemet bought them out recently.
It looks like HMCAD1520 can sample 4 channels in precision mode at 100 MSPS. Since they use one chip per channel (to get 1 GSPS in 8 bit mode), I wonder if they sample the same channel 4 times in 14-bit mode, maybe squeeze a bit more SNR.
Dave should add a stopwatch in the background of the fast speed reassembly. I'm always interested in the amount of time it takes to put stuff back together. That's typically the point where I regret taking something apart.

.... when you use a sundial?
I can understand the feeling.
What is up with the isolation slots on the DMM portion? Dave mentioned them, but could someone (Dave?) elaborate?
I am not impressed of that scope . The build quality is awful , the software and the multimeter are bad jokes . Would really prefer the RTB 2000 series from Rohde & Schwarz even with the glossy screen which I a not a real fan of . VGA output is also old fashioned , the HMO Compact Series offered DVI output and the design of these are some years old . There are absolutely no points to buy this scope , even for half the price
The VGA output is puzzling. Is there really anybody who'd want that? 
Makes really good sense in school setting together with a projector.

If you don't care about vertical resolution, there is no point. If you do, I would challenge you to find one even at twice the price with even 12 bit.
So that brings up an interesting question. Say you want 12bit (or higher) high speed sampling, but don't need a full blown oscilloscope. What is the best lower cost option in this price range for a data acquisition system with similar specs but not the front end or extra fluff like multi-meter and ARB?
Picoscope 5000 is a USB scope with somewhat similar specs. Beyond that, there are various data acquisition cards from National Instruments, Gage applied and others.

Those are generally more expensive, $5k and above, for high bandwidth devices. On the other hand, the USB scopes (Picotech, TiePie) are comparable in price ($1-2k). They actually use the same ADC chip as the OWON scope. Dave did a teardown of the Picotech 5000 a while back, it showed one ADC for 4 channels, while XDS3202A apparently has dedicated ADCs for each channel. Plus you get all the knobs, display and (optional) battery- a better deal than a USB scope.

And how about connecting a framegrabber so you can record signals changing over time?

but you don't get to use the exceptional picoscope software suite and you are stuck with wathever spaghetti they cooked inside the owon

I haven't used the Picoscope very much, so can't comment on the "exceptional" software. It does have API functions that can be used for real-time data analysis on a PC, so its more like a data acquisition system. For diagnostic applications of a scope for me having real physical knobs even with somewhat deficient user interface is better than software controls.
Recent updates modified the user interface to be more 'touch screen friendly' and i have to say it's much better to use with a mouse too.
At work i have a very long desk, which is divided as such: colleague - final test area - soldering area - me, so the board is always near my computer. It's very convenient to have the data already on the computer when i need it. Also big screen, etc.
Hello everyone!
What is this connector? Is it JTAG 10pin debug port for AM335?
