T5 sticks are difficult to take apart, primarily because to unscrew the top you have to use a long pair of needle-nose pliers to reach inside the deep grooves. This is after unscrewing the bottom portion off, which is the easy part.
Best bet imo would be to get a Madcatz SE stick and mod that badboy up... Plus its smaller, making it easier to manage and is only 50-60 bucks vice 150...
