seimitsu’s and sanwas’ are both top brands and it basically comes down to preference.
have you determined if you want something like a modded Hori with seimitsu parts or a custom box, ps ds pcb (playstation dualshock printed circuit board), and seimitsu parts?
there’s usually a difference between the two as far as price. since you haven’t said what your budget is, it might be something you should consider.
also, it’s a bit hard to tell from your graphic but are you asking for an american-style button layout (like US streetfighter machines)? if so, that’s most likely going to be a custom box job since hori’s only use japanese style button layouts.
since you want some sort of art on your stick, you probably want lexan/plexi (the plastic layer protecting the art).
keep in mind that most stick builders are not graphics guys. ask the builder if he can do a gouki symbol and how much it will cost. most of the time, you will have to go to the image mishmash section and request custom stick art there (which will take time since everyone is requesting something).
as you can tell, there’s a lot of consideration that goes into a stick, even if it isn’t fancy. imho, your best bet is to go with a pre-modded stick with sanwa/seimitsu parts. they are relatively inexpensive and quick to get (if someone is selling)
if you are going for a full custom stick, make a request with one of the builders (be sure to ask for the dimensions). while you are waiting, go to the image board, request some art (give the artist the stick dimensions, button layout, and specific details of what you want). as soon as the art is done, relay it back to the stick maker so they can have it printed and finish your box.
