Hi eveninggown, I got a delta printer so a Bowden Extruder is the only way to go really, you don't want the extruder motor on the hot-end carriage.
But it's also more tricky to get the pressure right because the filament has to be pushed through the tubing, I used a few solutions before I decided to build my own.
You are welcome to try it out yourself Kis Bowden Extruder
