I use a Makins.
I used to have a Walnut Hollow. Extruding for me was this horribly taxing job that would leave my hands hurting so bad that sometimes I would need a full day to recover and be able to use them normally again. I had to hold the barrel using one of those no-slip-grip cloths and crank hard.
Not so with the Makins extruder. I actually had in plan to get a drill adapter. But after using the Makins for the first time, I realized there's no need.
Me, with my problem-ridden hands, I can use it with no issues whatsoever.
Anyone wants a barely used Walnut Hollow set? Pay only for the shipping and it's yours.
