Okay, here are the final prices of my modded ftos:
$30: Sanding down all pieces and cutting excess plastic, and moding the core (makes the cube turn a lot smoother and less lock ups)
$35: Sanding down all pieces and cutting excess plastic, modding the core, I also install washers and springs to improve the cube
$40: Sanding down all pieces, cutting excess plastic, installing washers, and springs, modding the core. And also setting up the cube and break in
NOTE: I do not apply taxes to any of these options. And I only ship to the USA, depending on where you live in the US, shipping would be anywhere from Free-$3
Please PM me if you are interested in one of these
