I'd agree the aftermarket Bosh sensors suck, I went through two of them
on one of my previous cars before I went back to Mopar and had no more
issues.
The OEM sensors (at least on my '95) are made by Delphi. I ordered one
that's marked as the "actual OEM part" from Amazon.com for $37. The one
I got was the last one in stock sold by Amazon (free 2 day shipping with
Amazon Prime, whee):

This should be the same for all '92-95 models, I'm sure there's
different ones for the '96+ models considering you have two of them
being OBD2.
OBD2 you have to watch the O2 sensor wire length closely, it's easy to
get one too short or that doesn't have the proper heat shielding to run
to the after-cat sensor bung. I know on Neons people have gotten the
wrong ones before, then had the wiring melt to the exhaust. Then it
shorts out, pops the fuse in the PDC, and as the O2 sensor heater
circuit and the fuel pump are on the same fuse in the PDC the car
suddenly dies and won't restart as there's no power to the fuel pump!
