I know a 31 year old man that lives in his parents basement and has a huge 1/6 collection. HT, Enterbay, Ones Customs ,stuff you name it. The bad thing is he makes about $25 an hour. So, yeah.
So he has to work like 10-12 hours per doll. That's nearly two work days per doll. So he can max out at 3 dolls a week. If the guy gets more than 12 dolls in a month, he's max'd out his earnings.
Perhaps that's why he lives under his parents.
