Quality. I can pay a few bucks more per roll if it means not spending an extra hour cleaning a nozzle and re-calibrating, or prints that are trashed from separation of layers or bad adhesion. I keep ordering the same brand in white for most structural prints and leave the colored stuff for artsy knick knacks. Either more quality filament brands need to come out, or an extruder that can handle all the garbage you can throw at it.
In order of importance to me:
Consistent availability (not being out of stock when I need it most)
