>>6730921>>6730924>>6730936You are lucky, at least the bottom two are 1/4, the one at the top is 1/3.
Not sure if you know what is what, but the first one is an Angell-Studio Jimmy. Second is, if I am correctly, a LUTS Kid Delf...not sure which one.
Number three is a Unoa Lusis.
Unoa Lusis are easy to get nowadays through "Unoa Alchemy", they sell B-Grade kits with small flaws for a good price. Good as in, compared to how crazily expensive they were in the past. They currently have them on sale for 38000 Yen (incl. shipping).
Anyway, your preferred aesthetic is popular for 1/4, which means you got a wide range to pick from with different prices, some of them pretty low. A new Kid Delf can be bought for as low as 230$ (without shipping and blank though), less if you don't mind buying second-hand.
If you had posted something like pic related the whole thing would have been a lot more difficult.
