Direct Drive Options For Prusa i3?

Hi everyone
Sorry if this question has already been asked but i have a prusa i3 with a j-head hotend using 1.75mm abs. Im currently using a bowden setup for the extruder but im having some print issues which i believe is caused, at least in part to the bowden setup, so im wanting to try a new extruder. Since im using 1.75mm filament i dont think i need a geared extruder so im wanting to use direct drive. Does anyone know / use any that are good? there are afew on thingiverse but im not sure which way to jump.

Any suggections would be great

Kind regards
Chris

Start with the makerbot upgrade direct drive, i personally didn´t like it but I´ve seen it in use from a lot of people.

Hi, thanks for your reply, i like the look of the makerbot upgrade versions however as the are designed to run on the makerbot im unsure how i would adapt it to fit on the vertical x-axis of my i3, i was also checking out this one [www.thingiverse.com] it looks good however im worried that all the weight overhanging at the front may cause issues

Look at the PG35L Microextruder V4 on thingiverse. (http://www.thingiverse.com/thing:39098)

I printed one at it looks to test fit fine on my Makerfarm I3 - I have not tested it yet as I am in the middle of a
bunch of prints for my robotics team.

What did you end up building? Hows it working?
