Since I am modding consoles to my cabinet, I am currently using my cab to test my builds.
I dont like to use my cab as a testing station.
Therefore, I am looking for a small and cheap supergun, that allows me to test my consoles on a seperate Monitor and joystick, - so if something goes horribly wrong, the supergun will blows, and my cab will still be alive.

I got no experience whatsoever with superguns. Can you recommend me a cheap one, and tell me witch additional tools (e.g. atx powersupply, joysticks) I would need?
I want to use it on an ordinary TV or commodore monitor, pal, ntsc, RGB would ok. I 'd like to use an ordinary console joypad, sega megadrive joypads would be perfect. The cheaper, the better - I dont need high quality, as it will just be used for testing.
Can you tell me what I am looking for?
Thanks in advance,
ninn
