beaks is a good place to get the itr bar w/ a beaks kit, which you'll need anyway.
I got neuspeed front upper, front lower and rear lower (tie/strut bars) used off of ebay. I'm pretty impressed with the quality and the overall improvement in handling/feel of the car. Definitely worth getting, but definitely NOT worth paying full price. Used is the way to go.
I'm sure you already know, but don't go with cheapo brands here, and don't go with DC sports.
