I'll second the TRP RRLs. They feel good on the hoods, and the hood angle (and to a certain extent the brake reach) is adjustable via a plastic spacer. As Jeff said, the built-in quick release à la Campagnolo is really nice. Build quality of the TRPs are top-notch, with fairly tight tolerances and no weird sounds when riding over rough chip seal. Finally, they're one of the few modern levers that one can get with gum/natural rubber colored hoods.
A close second is the Cane Creek SCR-5 levers. They're essentially copies of the Campagnolo Gen 2 Ergopower levers (except without the shifting guts, obviously), so if you like those, you'll like the SCR-5. The SCR-5 also comes in a compact model, aptly named SCR-5C, with shorter reach for riders with smaller hands; that variant is quite hard to find. Unfortunately, Cane Creek discontinued the gum colored hoods.
