Well I have a nice Sony brand one, but I dislike using it because I have to remember to charge it haha. It wouldn't be so big of a deal, but my PS3 is like 10 feet away from where I play...and I generally don't just leave my PS3 on without me using it. I charge it while I watch a movie on netflix but I forget a lot.

I guess I could search for the one I had, it was great and worked great, but when I was replacing the batteries the spring fell out. Thats the only problem I ever had with it. Actually, thats whats making it broken now. I threw it and the spring is lost lol.

Edit: Also, the official ones are more like $50 unfortunately. If it were $30 I'd do it in a heartbeat. And get a charging station so it wouldn't be a problem.
