I have also tried most extruders on the list but am a huge fan of Johann's extruder. Yes, the geared stepper takes a big chunk out of your budget but it's a beast. All my direct driven extruders eventually fail. Bowden setups just have more drag. Speed is in my opinion not an issue. I drive mine pretty hard and fast and they do so 24/7 (for 4 months straight now!) and the extruder never fails (it's always the hotend that gives headaches). I sell both the geared steppers and the spur gears needed in my shop. The spur gears also really bite into the plastic and don't wear out. Other brass gears eventually got worn in. Ours are made in-house from stainless steel and on a computerized CNC machine. I agree, price is steep but you never need another setup again. Combine it with Johann's extruder head or Griffin's and you're done. Remember, if you pay peanuts you get peanuts.
