I have a 2007 Scion tC. So it looks like one of my TPMS sensors has died because my tire pressure light has turned on and won't turn off. I have checked and double checked tire pressure, checked for leaks, tried to reset the light.

Its my first rodeo with tire sensors. At this point it makes sense to replace all four sensors. However, I wasn't expecting to spend $80+ a pop for each OEM sensor. Have any of you bought any aftermarket sensors? Which ones would you recommend?

I'm a bit skeptical because the prices are a bit more reasonable, but sometimes you get what you pay for. Plus, it seems all websites that sell them don't accept returns. Thanks in advance!
