Factory stereo for 2002 Impala?

Where can I find a deal on a GM factory stereo for my 2002 Impala? A (Cassette and CD combo) Also, If I change the stereo will it lock up keeping me from installing a GM stereo in it's place?

I would look on ebay for one. I bought a cd/tape combo on there for 125.00. When i installed it, it said lock on the radio, i took it to the dealer and told them it was in there and i disconnected the battery to replace the plugs or something because it said to in the haynes manual. THey where like ok, plugged something into the diagnostics thing and unlocked the radio :)

Let me know if you need help locating one on ebay....

I dislike auctions is it possible to buy one online? And whan I buy one will I have to disconnect the battery cables to unlock the radio after I replace it?

you could probably find one at a salvage yard, also.

Thank you.
For you time and advice.
