I felt the same way about the plastic fixtures so I ordered 6 of the nickel plated reading lights and one of the flush-mount down lights from my dealer. . . all CCD or AS components. I used them to replace the plastic fixtures on the bottom of the cabinets above the sofa, the dinette, and the bed. The single flush-mount I used above the sink in the galley, again replacing the white plastic units. I kept the plastic units on the ceiling since they are barely visible and rarely used, and I kept the ones mounted inside the various cabinets and in the john. The reading light fixtures are a bit spendy, but they really look right, since they match the nickel finish of the cabinet hardware in our Safari LS.
I'm still looking for something better to replace the plastic one above the sink next to the toilet.
