Look at a few online sites:

Amazon: https://www.amazon.com/s?k=Rain+Jack...&ref=sr_nr_n_1
Jensonusa: https://www.jensonusa.com/search?s=p...&q=rain+jacket
Wiggle: https://www.wiggle.com/mens/cycle/jackets?o=2

Lands End: https://www.landsend.com/search/S-y5...PriceLowToHigh
Endura: https://www.endurasport.com/mens/c/m...%3ARoad%253B1#

You get the idea. I browsed steepandcheap.com and voler.com but saw no real deals there for rain jackets. I have an REI rain jacket with the pit zips. Its good when I need it. Nothing is a panacea and most will not breathe well so will act like two layers and make you sweat. It is what it is. Like another poster said above, I'd also rather be hot and sweaty than cold and wet.
