I used the E3D Slimline (1701HSM140AE) on the extruder, and the High Torque (1704HSM168RE) on the axes. All are 0.9 degree steppers, and of very high quality. Don't forget to adjust the drive current. I set mine to 75% of max rated for all four motors, which seems to work well.

I'm currently working on a completely different extruder design with a Sanyo Denkin NEMA 17 stepper that is only 10 mm thick. The entire extruder and hot end should come in at under 100 grams, although my current setup is direct drive and has no issues even at 300 mm/sec.
