Back in Switzerland I've been involved in the RepRap project, and made one or two contributions to all those cheap Chinese 3D printers out there, of which one should arrive in a week or two :-)
my friend adam started with a cheapo USD 150 reprap design off of taobao. i helped him build it in his flat in HK, then went back to TW
6 months later, by the time he was done he had upgraded it with USD 1,000 of parts (at *china* prices), including a 2020 T-shaped Frame you could literally stand on, ball screws, a Flex3Drive, MGN12 linear rails, 24 v power for the steppers, and a 240v AC heat bed.
all done iteratively from a knock-off design that barely held together and yet he still uses the incredibly dangerous RAMPS 1.4, with fans blowing sideways under the steppers.
astounding :)
