I put an AEM wideband in my truck. I'd heard good things about them and am happy with mine. Here's a link to the one I have
The only reason I'd recommend getting a wideband is if you are planning on getting a custom tune for your truck. If you are not getting a custom tune or doing a cam swap I can't see much use in getting a wideband of any kind. Unless you just want one for the hell of it.
