Quote from DismalAmoebaWow, I've always wanted one of those! It's the only cool looking GBA Micro. It's a shame it can't play Game Boy Color and below games though. You could try buying one of those scratch removing products, but I'd be careful.
I don't really trust scratch removal products. They're usually meant for glasses, which aren't made of plastic glass, or DVDs, which is specially designed material.
By the way. Searching for them at local trade shops is a good way to find them. I got mine for 70$ and people sell them for 120$ when they're chewed up.
