Chris, I have one of these spoilers sitting at my house, I bought the unpainted version because it was the safer option instead of getting one that was pre-painted in case the paint job was bad.
I'm really considering going for the OEM STI spoiler at the moment, so if you are interested I can send you my one for cheaper than the ebay link.
Mine is also probably the best of the spoilers from that Ebay link above, as I mentioned to the seller about Sammy's spoiler having some defects etc, so the guy found the best one that he had and sent me that, he also tested the brake light before sending it out too, because Sammy's was faulty and had to get a new LED light replacement sent out.
The reason I want the OEM STi spoiler is because I am pretty meticulous with my car, and I want all the parts to be genuine. I'm also considering getting the OEM STi front lip as well, even though I also have the unused ULTREX replica sitting in it's box in my spare parts room.

Hell if you wanted that too you can have for a good price as well!
Although I'm not looking forward to Subaru ripping me off with their OEM parts prices.
This one is still in the box and brand new, only took it out to have a look at it to see if there were any ripples like Sammys, which there wasn't.
Let me know if you are interested.
