I just recently bought this car. the oil light comes on and beeps for about the first 30 mins of driving. when its warmer it seems to stop and then it will intermittantly come on and beep again. Does this mean the car must be services, or is there something esle wrong.

Was the oil pressure checked under a load when the car was accelerating if idle oil pressure was good but lower when the vehicle was under a load it could indicate a partial blockage of the oil pump screen and a posting of the oil pressure numbers would be helpful if you are satisfied with the numbers and the test was done properly and the switch replaced you have a problem with the circuit
there is a sensor in the bottom of the pan that checks oil leavle they get gumed up and stick next oil change you can pull it out and clean somtimes this helps if it dose not loked gumed or stuck replace it
It blinks and beeps if the oil pressure is dangerously low , which could severely damage your engine. Hopefully it is just a faulty oil pressure sender unit. That is an inexpensive sensor that "measures" the oil pressure. Best case , engine fine , oil pres good , just a bad sensor.
I've never seen an oil pressure sensor that costs $750...Likely something else was done to justify that cost. If the light has not come on since the repair, I'd assume that problem has been corrected. If not, have the thing checked out again. If they charged you to repair it, then it should be fixed or, it's their problem!!! You should not be afraid to drive your vehicle. It's a machine, therefore it can and will break sometimes as do all cars. But being afraid to use it is not a solution.
Chrysler mounted the oil sensing unit on these motors directly above the oil filter. It is very easy to accidently hook the sensing unit with the oil filter wrench and crack or break it. For anyone whose oil light problem developed right after an oil change, this may be the problem. To change the unit, pry up the plastic retaining clip with a screw driver and unplug the wire harness. If the plastic part of the sensor is broken, (or if you break it to facilitate easy removal), you can remove the sensor with a 27mm socket. Once you have removed it, use a piece of CLEAN pipe cleaner to insure the hole isn't plugged with sludge which could also cause the oil light to come on. Screw in the new unit finger tight, then snug up with a WRENCH. You cannot use the socket to tighten it as it would damage the plastic part of the new sensor. Plug the wire harness back on, then start the engine to make sure it doesn't leak oil around the new unit.
