Aftermarket Headlamp Assemblies that fit properly and don't leak

Looking to replace the headlamp assemblies on my 03 Impala LS. Most reviews I've read point to condensation buildup and less than a proper fit in the area of the retainer clips. Which brands and/or models should I be looking at to minimize some of these problem areas? Thanks.

i bought these in april 2012(had to look in my order history to find right seller)

one of them leaked and the seller replaced it insanely fast. the coating has peeled off recently and i had to wet sand and compound polish back to new.. the bulbs that came with it all still work and i would buy again.

you should buy some new clips, they werent included and my old ones were brittle. i have a 2004

there is a 5 star review from CBattista, that's me.
