Well, I gouged up one of my rear rims... F%$#!!!!!

Someone cut me off coming to a light... guess 3 sets of signs and paint on the road wasn't enough to help this idiot figure out where he was going. He was in the right turn only lane as we approached a green light... I stay in the straight lane and begin to accelerate up to the speed limit to go past him when all of a sudden WTF! I see him start to come over and one flash from his turn signal. He's half way over and the light turns yellow so he slams on the brakes. I yank the wheel to the right and get in the right turn lane (I could have gone either direction my work is on the opposite corner). I pull up next to him, roll down the window, and give him "Are you F----n kidding me? Thanks alot, don't let me get in the way." Now the fun part, (well not really) I put on my signal and make my right turn not paying attention to how far up I am and KERRR THUNK!!

my back tire slams into the curbing. OH CRAP!!! I get into the station and get to see my handy work pictured below.
I learned my lesson, I should have just followed the idiot across the street to where he parked in the bus station, called for a unit to meet me, and given him a ticket for improper lane change, but no I gotta let my frustration out and try go on about my merry way. Either that or I should have just let it go...
My question is..... SHOULD I GET A NEW WHEEL? I am pretty anal about my car and like my wife says I won't be happy until its fixed.
I have a bonus from my GM card ($500) sitting on my desk (that I was saving for a few nice mods for the car) that if I use it, the wheel will only cost me about $62 plus mounting. To get my wheel fixed was about $335.00 and to get one off ebay will run me $250.00 to $300.00 then I take my chances on its real condition if you know what I mean.
Can someone also please tell me why all these GM parts places charge a core charge of $50.00 for your old wheel? Its my wheel, I paid extra for the polished aluminum, why should I have to pay $50 extra to keep it?
Of course all this depends on if nothing else is wrong with the rear end of the car, then I may want to get my insurance involved. I am taking it to my buddy's shop tomorrow, after all this rain stops, so I can spin the wheel to make sure its not bent and put the car on the alignment rack since the hit made the ass of the car kick sideways.
