I searched around a little bit and it looks like
www.cruiserbits.com has the best price of $239.95 ...that's for the non-turbo, and since you posted in the non-turbo section I take it you don't have one.
As far as polished billit or chrome on silver....I have bits of both (billit licence frame / chrome bumper inserts) and you really can't tell the difference between them.
Here's the direct link to the grill at Cruiser bits...
