> All I can say is the $75 one works well from Bus Depot.

Actually. For an '86-up (2.1 liter) we don't have a $75 one. We do have two
"splice-on" Bosch ones that work just fine - one for $39, and one for $59
that comes with its own waterproof splicing kit. (Perhaps that's the one
you're referring to.)  Also we have the ones with the correct factory
connector already on, of course. And we have the factory shield to keep your
new 02 sensor lasting longer. 

2.1L options:

1.9L options (a bit cheaper, as they're only 1 wire):
