Pretty slick...it appears that the curved drawer materials are the biggest multiplier of price. The 2-door model with short drawer sides is $2880 while the 3-door model with taller drawer sides is $4700.
The hardware for both of those styles is readily available, has been for years.
The only real challenge here is bending the drawer sides. There are several ways to do that too.
This would have been every day stuff, back when I was still working.
