Hey Eric... the CE28N's have been copied by Rota and sold so widely, they're actually common looking to me these days.
What about the Enkei GTC01's in 18x9.5+38? Too similar to the stock wheels?
On the other hand... I still love TE37s, even though they've been copied a bunch:
I like 'em so much, I put the cheaper Konig equivalent to the TE37 (Konig Spooled) on my Miata:
Also, the OZ Alleggerita's are bad-ass simple looking wheels. These are what I would have put on the wagon if I had the money to spare at the time, though I'm not sure if they come in a good wide fitment for a new STi:
