I could probably write a lot, we outsourced for some time and I saw how Juki / Yamaha assembly lines processed our PCBs...
Chinese lower end are better serviceable with standard parts by yourself I'd say, we have built our own machine in Taiwan (with the background knowledge of the Mechatronika MX80 since we disassembled the machine back then, and used relatively inexpensive parts too), the serviceability is in our hands now and it's a nice feeling to have everything under control.
Mechatronika is very much a standard machine just like the chinese ones. portal + Z / Theta that's it (while the chinese ones have multiple heads at least). There are so many servos out there which can be used, however Delta really shined with their international support (trying to help sorting out our Mechatronika problems which was not even their job).
The Mechatronika Machine offers far less value than chinese machinery, spare parts are a rip off (and can even be manufactured as single parts even cheaper than you buy it from them - eg nozzles, from professional CNC companies you can get 10 for the price of one from Mechatronika, the chinese Juki nozzles are also okay; I did not experience magnetic issues or a runout (the runout that applied in my case was my own mechanical calibration problem, and not related to nozzles bought from china)).
If you can go trouble free with a chinese machine for your products it's a big plus, certainly not all products are suitable for those mid / low range models and might require more rework after the pick and place process.
The Juki / Yamahas which were used for assembling our products were close to trouble free the PCBs that came out of it were 99.9% spot on and required very little rework if at all. The main issues were usually related to stencil or reflow oven -- so experience (and preparation) of the operator mattered. eg. baking parts, reflow oven settings have to match with IC specs, the reflow ovens have to operate in a calibrated manner.. it call can go out of calibration if sensors have issues.
Would I go for Juki / Yamaha / ASM for our products? Probably not, even our own machine is idle for over half a month. It has to work when we need it that's all.
Would I go for a chinese machine? With our background knowledge, our software and existing machine blueprints now, also no..
I'd rather build a second machine and chain them up.
For a beginner with less money I'd probably advise to go for a chinese machine, and maybe spend one month in deeply understanding the machine (you said you wrote your own software for it, I just don't know to which extend and what your requirement is, finally you wrote you're using a Hanwha.. so your requirement might be accordingly I guess).
There are many variables that might apply in deciding which machine to use... Some might get away with machines without vision while others badly need it.
Not having to deliver components to an assembly house, waiting for a slot, counting, assembling it taking them back and again is a big plus and time saver.
