I bought this Acmaxx LCD protector on eBay, I'm quite happy with it. Cost was $19.99, free shipping in the USA. Fit is perfect, it lets most of the light through, and it has a chrome edge that looks stock on my black E-PL1, it should look good on any of the colors. It looks better then the sample picture. I figured I'd share in case anyone is looking for one!
