Looking for a strain wave/harmonic gearbox

I’ve spent the last few weeks scouring the internet for harmonic gearbox OEMs and to be thorough I’m asking for your help to make sure I’m getting the best price possible.

I found an 1.6kg 85mm OD model @ ~76Nm torque for $500usd and a 2.1kg, 105mm model @ 160Nm for $580. The size, torque, and mass are critical. Unfortunately based on market research my bidding price is $250 averaged.

So with all your collective experience, do you have a lead on more affordable models?
