13 mini's wow. You should post a photo of your collection. Maybe in the crawler thread though.They can add up, but if you do it over time you don't feel it. Problem is most people binge shop and try to do it all at once. They are quite addictive though. I have four 1/10 crawlers and 12 or 13 1/24 & 1/18 crawlers. I'm kind of addicted to the mini's.
