Thermo king tripac evolution waterpump oem alternative?

So my apu just had its water pump decide it was a good time to die on me, cant even repack the bearing impeller cracked as well. And currently they are sold out all across the u.s and unless we have a friendly snow mexican someplace willing to call around up north and help send me one..... im left with most places here in the u.s 4 to 18 weeks out to get me one.

However, i have found a few chinesium grade ones to get me by till they either fail or i can get a new or rebuilt oem one. and im curious if anyone has any experince with them? Ive heard mixed things and dont want to purchase one only to find out it doesnt work. Any advice would be helpful.
