Just a heads up, if you aren't used to playing your shooters on a stick, expect a time where you need to get used to playing them as such. It's definitely a better experience, but feels weird at first if you're so used to holding a pad in your hands.
You likely fall in that catagory, so you probably don't even really need to go with swapping parts out and such (easy as it is). Just get a Fightstick and call it a day. They're just fine with stock parts in them to anyone who doesn't know the difference. Once you do start changing things out though, it's tough going back to sub-standard parts.
Just my .02 cents.
