I posted up about my little "homemade" sills project a few days ago but will again FWIW. Not to cheap out but I didn't want to spend $85-$125 or more for sills so I got some blank aluminum ones from a seller on ebay, some Camaro decals from a different one, clear coated the combined results and installed them. The chrome/red combo go well with the chrome/red RS emblems on the front & back of my 1LT RS. Like I said then, I know I'm biased, but I think they turned out nice. Oh yeah,
total expenditure for everything: about $25!
