Old Nomix 5400822 diverter stem I need to replace 20 in this apartment building. They are $71.00 each can I buy them somewhere cheaper

Take one to Home Depot. Or Loews, or any appliance store for that matter.

Please open the link below will give you all the info regarding call them, NoMix Valve Cartridge is warranted to be free from defects in material and workmanship to the original owner of the property only, good luck

Looking at John's link and it sure looks like Mixet cartridge to me. Home Depot sells Mixet cartridges for around $20.00 each. Call them up and verify

I would call them before going to Home Depot if he can get them for free why not, Thanks.

@ John: Absolutely, free is better than paying for it. Also, it challenges the manufacturer to live up to his warranty.
