I used to have a cheap PS2/PS3/USB Mayflash arcade stick:
I modded it, so I used my own designs, my Seimitsu joystick and my Sanwa buttons.
Now it looks like this:

The problem is... I was young and innocent and I didn't solder it that good. So, as I see there are Zero Delay cheap PCBs that do not require me to solder, I think they can be an option.
Which PCB should I buy? What things should I consider? Note that I would like to keep its console support.
Also, I don't know what to do with the buttons in the front (Auto, Clear, Select, Start). How can I do to connect them to a new PCB?
Thank you very much!
