It does cost more per print but not that much more to use the Strat. Mostly its just a big "emotional commitment" as people are afraid to take risks with so valuable a machine.

The others go non-stop. 1000's of hours. They are so cheap, and so ubiquitous that there are the equivalent of 2 more printers worth of spare parts in bins under each one.

People are forever experimenting on them with different nozzle sizes and arrangements, custom firmwares, wacky filament blends etc. We've made some wild, wild stuff!
