This is pretty much exactly how I looked during my five-year adventure in retail. I would get texts from outgoing employees asking if I was alright since I looked miserable. I was working in the hellhole known as retail, what did they expect me to look like? Miserable was my default expression.
$280,000 price tag severely dampens that mood. I degrease, strip paint/rust a lot of metal daily, as well as cleaning old surplus gun parts for my side hobby. I might try my hand at building one of these myself. The nice thing with online electronic and part suppliers is that there is rarely any new tech you cannot replicate on your own given enough time and testing. Sure would beat the noisy and bulky bead blasting cabinet that probably gives you extra emphysema with every use.
EDIT: Eh... after shopping around my total cost would still be around 7,000... I guess I can live with a little dustiness for a while longer *cough cough*
