To add on to what I said before about modding the DOA/VF stick since a lot of people recently got the VF stick. Here's a simpler mod to make the joystick feel better by adding a sanwa octagonal or square restrictor plate to the stock Hori stick.

Best places to get the parts would be Lizard Lick Amusements or through ponyboy at SRK's trading forum.
