Here are my 3 sticks (from left to right):
The Dragon Ball Z stick, created by Nuby, features Analog input. I tried Sonic Adventure 2 with it and it works. I bought this in hopes of playing Smash Bros with an arcade stick, however, two adapters from Mayflash that I tried apparently force the Analog mode to always be digital (as indicated by the Analog LED).
The arcade stick by Mayflash has both a PSX/PS2 port and a USB port. I don't really like the noises that the buttons make upon pressing them. Pressing 9+10 at the same time functions as the home button.
