I'd be having someone look at that first tbh mate. Mightn't necessarily be the sensor, sensor may just be receiving bad reading from cat or further up the exhaust system. It's a common enough problem for mechanics to just replace lambda sensors when they see them mentioned but they may only be showing the problem, not the actual problem itself.
