Track Lighting? [1M]

Hi.
I have a question about lighting in our units. Because there is no overhead lighting beyond the ceiling fans, we were thinking about adding some track lighting. Has anyone done this with any success? Did you do it yourself or have a professional come in? Any brand names or stores to suggest? We'd prefer not to blow the budget out on this...esp since I don't know if we'll take it with us when we leave...depending on how permanent it is.

Any help would be welcome!

Thanks!
