the strooder is a neat bit of kit - seen one working.
If I were to get one now - that's the one I'd get.

Given the high price of extruders and the low price of filament - also that many filament makers will happily do custom filaments - I just don't see the need for home filament making.
It's not currently particularly cost effective.
Also most of the really good filaments are not pure pla or abs or pet etc. They do have modifiers that make them stronger, bendier etc.

Give it a few years and it'll probably be worth doing - but currently, I don't really see the point :-)
