Thats still mega creepy dudeI wasn't sure but I was pretty sure the TL kinda flipped the sentence (he was supposed to mention her looking like a doll prior to that sentence, but it's reversed). I wanted to be sure so I read ahead to chapter 2 before replying, and it makes more sense after reading it. Sure enough he is just really crazy about dolls. He meant he would buy a doll that looked like her.
And yes, the "any amount of money" isn't out of place for a doll otaku. If you know how much high profile and/or life-sized dolls can cost. Like the FF14 Y'shtola doll for instance. $980.00 USD!!
