I use grey abs from Matter Hackers. Not the cheapest you can find, but it prints fine for me. https://www.matterhackers.com/store/l/175mm-abs-filament-grey-1-kg/sk/M2H0VP8H
Filastruder abs prints well for me. Way better than some others I have tried. I really like that dimensional data for the entire spool is provided. Proved accurate when using this to tune feedrate for each spool
