Looking for: Game Boy Light (Gold or Silver)

My Gumball machine’s average profit is 40$ Monthly. Anyone know where I can find an affordable Game Boy light? I’m not talking about Game Boys with less calories or those rare light boy accessories, or those worm light attachments for GBA, I’m talking about the rare Japanese Game Boys that have backlights. 78$ max, because 6,800 ¥ is about 78$. (Yen=¥ Dollars=$ FYI)

Price: $78 (Maximum)
