The starter copters are all infrared. You can get them with cameras. I'll bet the first hit on Amazon will do fine. Yup. First two hits are Syma and they're under $50. Now - a quad that will take a gopro is a whole 'nuther animal. That pretty much puts you in DJI territory. Worthy of note - if you want to fly around and take pretty pictures, you don't need a gopro hauler. If you want to fly around and get actual cinema moves (pan, tilt, zoom as you fly), you're not only into 2-person operation, you're kind of on beyond zebra as far as size and expense. The "I want to slap my existing gopro into an existing quad" market segment is kind of the worst spot in all of quadcopterdom. Get a shitty one to crash into walls, and if you love it, get a real one that won't haul a gopro and learn to fly. I recommend blade because pretty much every local hobby shop will have parts.
