I use the same one as Eric on the FB, except I use the stainless version. They swivel fine for me for at least a couple years, and when they start to bind up a bit I know its time for a $2 repair kit after which they swivel fine again. FYI I use 2 swivels, one at the handle and one at the boom. I use the cheaper rubber hose, theft is rare for me.
Based on recommendations here on the forum I've also tried the one 2Biz linked to. That one works well for me too.
I rarely get FB hose tangles but if I had to pick I'd say the fluid controls ball bearing swivel (2biz link) is probably better for the FB, but I only have a year or so of experience with it, the others I've used for 15 years.
