Inexpensive? not so.
$104/sensor = $416 (Nissan OEM, as aftermarket for 2012+ not yet available)
install and balance = $80 (dealer)
reprogram ECU = $50
Give or take after tax = $617
I'll deal with an annoying warning light for a couple of months.
They used to be $400 each once apon a time. Better question, what vehicle is no longer in the driveway besides the talon?
