Well I think you need another professional opinion before you go and buy anything more. Find out what the CEL exactly said. Where did it come from? How many miles are on your vehicle and have the sensors ever been changed?

If you do need the sensors, Autozone, yes Autozone sells the exact same BOSCH sensors with direct plug in end for a fraction of the price. (same BOSCH part number). fyi.
