Low ft-lb torque wrench (15-50)

With MH's excellent lending library, I have /almost/ all the tools I need to remove my Prius hybrid battery; the one exception seems to be a torque wrench that works in the low ft-lb range (20-30 ft-lb), which is required for re-tightening certain bolts when re-installing the battery. This would fill a gap in the current torque wrench options (have: 40-200 in-lb and 50-250 ft-lb; missing: 200-600 in-lb aka 17-49 ft-lb range), and would be helpful to me & perhaps other future Prius DIYers :-)
