The materials used appear better than most; stainless steel. $64 at Rock Auto.

Porous PTFE Filter - Allows atmospheric oxygen to enter the sensor without permitting water or engine contaminants to seep into the casing.
Robotic Laser Weld
Aluminum-Oxide Trap Layer - Keeps silicone and lead outside the ceramic elient through DENSO's exclusive design, preventing damage to the platinum electrode.
Stainless Steel Housing - Resists corrosion and contamination with a rugged, watertight body.
Double Protection Cover - Maintains proper unit temperature for quicker response times and protects the ceramic element against silicone and lead poisoning.
Corrosion-resistant stainless steel construction
PTFE filter blocks efficiency-robbing contaminants
Refined zirconia element improves sensor response
Superior design maximizes engine performance and fuel efficiency while reducing fuel consumption and harmful emissions
First Time FitŪ delivers the right part the first time
Ensures smog test compliance
Bosch OE for me. That's the same for almost all of the parts I put on my truck. If I can get OE (not BMW that's a rip off) I'm going with that. Most of the aftermarket stuff seems to be made in China and is crap. I've heard nothing but bad things about URO parts. Won't use them at all.
