An 03? No idea about the prices in your area but it shouldn't be too hard to find a place to plastic weld it for cheap. The price killer will be getting it repainted. Because they can't repaint just that section where the crack occurred they have to repaint the entire piece. So that's the whole tail section. It's probably a lot less trouble to buy a new tail section (You can get them pretty cheap on eBay if you're in the US) but it all depends on price I guess.
