Here are a few really common sticks (none of which I am purchasing):
Top: looks like my current PS2 Hori stick. Nothing special, but has lasted for years.
Middle: Real arcade pro? Sanwa or not?
Bottom: Looks like middle one, but just for 360
Hori also has the Soul Caliber themed, SFIV themed and a BlazBlue editions coming. Many mods made to them (posted in SRK), but I’m more curious the differences between them (if there are really any).
