Default Oxygen Sensors for a 03 Honda Accord?

My check engine light came on a couple of weeks ago, I took it to my mechanic who determined it was my o2 sensors. First question - He stated 3 sensors needed to be replaced, the Upstream, Downstream and in the exhaust. Does this sound correct? (03 Honda Accord EX 2.4L AT) Also, he priced me $300 for all three. I've been pricing myself and have found Denso is quite a bit more expensive than Bosch. Any opinions regarding these two brands? I realize fuel efficiency will decrease if I don't replace these, but how severe is the issue? Could I go a few more weeks, months, year? Last question - I will probably sell this car in 2-3 years, if I put on the cheaper brand (Bosch?) how long could I possibly expect them to last? Okay, really last question - Any suggestions for a place to find these at a good price? I really want to save some money here! Thank you for all your answers and opinions!

Bosch is fine. I would prefer that actually myself. You can go forever without o2 sensors. A lot of people just remove them so more fuel is delivered to the engine and it gets more power (that's the theory anyway but it's not quite that simple and doesn't quite work like that). $300 for all three doesn't sound bad, but it's an easy do it yourself job, unplug unbolt and reverse with the new ones. I doubt all three of yours are bad. Get it plugged in at autozone and they might be able to narrow that question down. They also can get you the parts for a reasonable price and usually carry Bosch products. I go to autozone for just about everything, if they don't have my stuff i consult rockauto
