Wow R3k for two joysticks! And I thought over a grand for the two Utrastiks was hectic! What joysticks is he using? eg, Analogue, 4 way or 8 way?
Had a quick look at the ultimark site, they have xbox adapters for their i-pac and all the hardware you would need for a two player panel with 8 way sticks comes in at just over a grand..
They also have a ps3 adapter tho if I where to do this I would just bang my utrastiks onto the i-pac.
So I recon if I where to build this thing with analogue sticks it would probably come close to R2k, tho I wouldn't sell it for that.
R3k sounds reasonable. <edit> IF they're analogue.
Most arcade joysticks are not analog, most of them are 4 way. Those very popular Sanwa joysticks are 4 way - they have 4 microswitches. In fact, someone even replaced the joystick itself with 4 buttons, works fine.
It will be an XBox 1 adapter, not an XBox360 adapter.
As I said, they are 4 way joysticks, but the Sanwa kind which are very popular in arcades. High quality japanese make. When I was sourcing parts, to get the parts needed to build 2 sticks, not counting wood, but including an Xbox 360 compatible PCB came to just under R3k including shipping. Plus, this guy can probably do a much better job than me, since he has done it before. So I think its a very reasonable price for 2 custom joysticks.
