2003 Grand Prix GT

Went to the body shop to get a quote on a cracked bumper, they told me they would need to replace the bumper and gave me a quote of $1k+ so I'm looking else where. I heard the guy mutter something about there being two styles of bumper for my car but the oaf didn't include that in the quote (just stated $400 for a reconditioned bumper cover). How do I figure out which style I have? Where can I get it? Is $1k reasonable for this repair? My car is silver (just like 75% of the Grand Prix GT's on the road) so is $400 for a reconditioned bumper worth it? Or should I try to find someone parting their car and buy theirs? Is this part easy to find?
