WTB: supergun for MVS 4 slot

i want to buy a supergun for a 4 slot so don't really need one with sound or control hookups as i have an offical stick and speakers.

also i have an rgb scart tv so dont need a converter for s video output, so the supergun is just for rgb video and power.

i think i probably need a custom supergun and would be up for making one myself but dont know where to get the parts or what parts are reccomended for this, so any input is very welcome and needed.

i dont really mind a temporary fix kinda thing for the time being but would like to get something of quality in the near future, but for now just want to check my hardware is working correctly and play my games.

i am in the uk but dont mind importing if it is a good quality supergun. but dont need one built into a stick.

thanks in advance for any help you can give me.

The 4 slots use both +5v and +12v, you need to use a power supply that outputs them.

thanks. i realize now i was thinking about the voltage like a home console. i have a changeable voltage psu but the minimum output is 12v so I'll be looking to get a new one, any recommendations?

Xian does is the difference in voltages for different models of 4 slot? should i really be discussing this in tech support as well?
