Honestly I have close to 10k in this machine, big hardware gets expensive quickly. But it's nearly all metal, should last forever. You could build one for much cheaper if you used wood or plastic or non-heated bed, but rigidity is an issue with larger frames.

Here's a few prints I've done in the last 2 months, run about 20 pounds of filament through this machine so far
