Rear Spoiler

My Mustang is a notch-back. I would like to find a rear spoiler for it, as I think it gives it much more of a sporty look. I could spend about $200-$300 US on a spolier from a Mustang parts company, but I dont really think it is necessary to spend that kind of money on a rear wing. Im sure that I could find one that would look just as nice off of a car at a junkyard or something. I was just looking for some opinions. What cars spoliers should I be looking for and what have some of you put on your cars? I personally like the ones off of a sunfire GT. Also, if any of you know of any companies that sell spoilers for a reasonable price, could you give me the company name? Thanks in advance for any help.
 
I saw one off a Cavalier or something (I forget exactly, might've been a Sunfire, even) on a notch once, and it looked pretty decent. I've also seen the notch/vert-specific Saleen wing, and it can look okay.
