Hi all!
First of all let me sort of introduce myself: I'm Floris, graphic designer, from the Netherlands and I'm currently in the process of builing an Xbox classic based arcade bartop cabinet.
Most of the parts etc. are sorted, but I'm running into problems with the 2 player controller part.
One thing I am sure of is that I want to stick on a "tight" budget so the X-Arcade controller is a no go.
For now I'm thinking about simply soldering my buttons and joysticks to 2 controllers, I have the following controllers available:• 4x Duke controller
• 3x S controller
• 1x "playon" branded controller (sold under a lot of different brand names, eaxus for instance)

I've read that the Duke- and S controllers are a pain to solder, next to that I would like to use the trigger buttons as well.
I could buy myself a few cheap controllers from ebay, but they might be just as hard to solder as well:
• Link to ebay resultsAnother option I've been looking into is a jamma to xbox pcb:• Link to ebay resultsBut I'm not sure if I can use this for the buttons only (without using the monitor connections etc.)
Edit: Just found yet another alternative the Arcade forge Dual strike encoder• link to product pageBut sets me back quite a lot (€ 70,- for 2 incl. 2 xbox to usb adapters)
In which case I could just as well choose the X-Arcade encoder:X-Arcade 2 Player BYO Arcade Encoder USB/PS2Combined with the:
X-Arcade Playstation 3 + Xbox 1 Adapter: 2in1But as mentioned I would like to keep it low budget and this adds up to $ 80,- as well.
All in all I'm pretty stuck at this point and I hope you guys can shed some light on thisThanks!
