Quoted from Homepin:
This is so wrong it made me laugh! You have only looked at hardware costs - how about $20~30K for audio, $20~40K for animations, $10~20K for artwork, $25~150K for programming and a whole heap of other expenses that are mostly out of your control.
That's well over $100K before you cut a piece of wood or order in a standard flipper assembly. How about interface PCBs (if you use standard PC hardware) and the many other specialised PCBs required - who will design them? Electronic engineers worth employing cost $80~150K a year. They are expensive EVEN in China!
Wow, you don't read the homebrew threads much. Ain't no way any of those folks have dropped 100k to build one machine in their garage.
