cases and protectors

I must say that this is the best you can buy for your GBA (which by the way is waaaaay better than the SP, I got one, used it lightly for a month and it looked terrible. Plus the charger intantly broke when I didn't knock it around at all. I bought it new, by the way) because it's cheap, and just plain useful, especially if you want to someday resell your GBA for the Game Boy Deluxe or whatever they'll have.

The screen protector is great, because I go up and downstate every Friday and Monday, so I need to while away the hours and know that the sweaty fingerprints don't touch my screen. The protector is awesome when the GBA falls (it happens, you know, it really does) out of the car on to hard cement, the one drawback being that your Game Boy looks like an armored tank.

The cartridge cases are veeeery useful so you know that Pokemon Ruby isn't getting filled with crud as you jostle your suitcase or backpack (portable storage unit, then) around.

Overall, this is the best thing you can buy, with the possible exception of the GBA game folio or whatever they call it.

Put short: this is a great deal. Buy this if you knock your GBA around at ALL.
