If you already have a universal remote, there are a few options around inc. the official Logitech model mentioned above. I have used an IR2BT since launch and it's a fantastic bit of kit coupled with my Logitech Harmony One (best remote I've owned). It works flawlessly but eats batteries, although can be charged by USB2 (not the PS3 as it's not always on IIRC). If you don't have a universal remote (I would recommend one though if you have a lot of equipment especially if you have an AV Receiver) the official PS3 remote is the one to buy. It's well laid out and the only downside for me, is that it isn't backlit so not much use in a darkened room with a projector.
