My Thing o matic is driving me insane (dot get me wrong ik worked

My Thing o matic is driving me insane (dot get me wrong ik worked fine for 1,5 years or so) but the MK6 hot end is giving me more and more problems (where jamming in that long tube). Also have my doubts about the direct drive system.

So what would be a good replacement ? any thoughts ?
I have a lot of 3 mmm filament so should be one of that type

(I still have a Huxley up and running btw so i can prints parts for it)
