In my real estate work I see a lot of lighting and I recently worked with a client that did a beautiful remodel of a mid-century home. They updated the lighting and they were able to do it pretty inexpensively by purchasing the lights from IKEA. Granted, not all of the lighting is great because some are a little tacky but they do have a pretty darn good selection overall.
There are some other expensive options if you go to the downtown furniture and design core of Western Ave. Occasionally you'll find some decent modern lighting at one of the big box retailers like Lowe's and Home Depot but it's harder to find in store. The online version of these retailers have so many lighting options you'll go nuts trying to narrow them down.
