mmm, they arenāt cheap. depends on hp, thickness, coating, drilling amount, etc. i think the most i paid for one was something like 58 for a 24hp panel with uv print. i can generally rationalize the cost when i build something because parts (and my labor) are cheap comparatively, but anyway
also, their shipping (in the US at least) is free over 50, so its best if you can do multiples in one order, and they can be totally separate designs too.
