Not sure where you'd find a '59 style kit. Most of the kits I've seen have a modern C profile neck.
The more specific high-quality kits with solid maple tops seem to come from the USA, and normally are body and neck only, with no hardware and are pretty expensive. By the time you've added shipping, taxes, hardware and electronics, plus your finishing material costs, you probably aren't looking at much less than a used Gibson Les Paul, which will be worth much more than your kit ever will once it's built.
