When my son was younger - about 7 years ago - I got really into making GBC contraptions with him. The hardest bits to find were the damn Lego balls! I paid someone on eBay $1 per ball for only 20 of them, not including shipping. I have no idea if it's better now, but I'm always amazed at the numbers of Lego balls the GBC events have. Where did they get them all??
