I wonder how much this entire setup costs is it like $20,000?
It is somewhat telling that there is more money paid on the computer - this is more a computer enthusiast who dabbles in electronics setup (not that there is anything wrong with it) - but if you're doing serious circuit design work you're going to find this setup lacking in many ways.

Easily less than $500 based on the items there's a glimpse of - probably much less.
> Do you think he buys each one in bags of 1?
I doubt it - that would be utterly stupid for passives and this guy doesn't seem stupid - if anything obviously frugal to a fault. I think there are too many corners cut - there is some bench equipment that is worth splurging a bit on. But even when you buy small quantities of SMT components they are usually cut off a tape - and in the US sold for a huge ass markup. It seems his bagging and inventory system is homegrown.
