I put handle covers on a couple weeks ago too, it definitely looks better without the chrome. I first tried some generic handles (not just covers, but entire handles) from ebay that were supposed to fit. The front handles fit, but pulling them open didn't feel as smooth as the OEM handles. And the rear didn't fit at all, so I went with the same covers J.A. installed:

IMO the handle covers look great from 4+ feet away, but they're a little tacky right up close. I might try to find some color-matched handles from a Limited. Hard to beat the price of the covers, though.
