[quote name='phreak5k']Anyone have any experiences with this product? I'm very intrigued in the possibility of get a larger nub and possibly changing out the D-Pad.[/QUOTE]
While I'm still curious about the d-pad replacements, I can tell you one thing for sure: DO NOT use anything to replace the nub unless it's completely flush against the PSP's face. I used a replacement nub that was rasied off of the face of the PSP (sort of like an arcade stick) and the leverage caused the internal portion of the analog nub to fall apart--if I wouldn't have had a warranty with EB Games, I'd be out $200+. I've heard the same story from several other PSP owners, so consider this your warning.
