I need help! Which upstream O2 sensor do i get for my 2000 crv EX? So many to choose from. This is my 3rd request for some sort of answer. I cant afford $300 for a factory replacement. Whats the deal!?

Denso makes an "exact fit" replacement that includes the correct wiring harness connector.
Autozone has the upstream for about $83, and the downstream for $113.

I would avoid Bosch. Along with the weirdness of putting German parts on a Japanese vehicle, I remember reading about problems with Bosch O2 sensors in CR-Vs.
