The 17HS19-1684S (see [
www.omc-stepperonline.com]) is a popular choice and suitable for use with most electronics. If you will be using Duet WiFi electronics then you can take advantage of the higher stepper driver current rating and choose the -2004S instead with the benefit of higher torque. If you want extra positioning accuracy, you could choose the 17HM19- versions instead which are 0.9detg/step, although on an H-bot printer you probably won't see any difference.
There are other brands/models of stepper motor with specifications very similar to this series, i.e. 1.68A or 2A rated current and about 3mH inductance.
High torque and low inertia don't go together, because longer motors have both more torque and more inertia.
