Lumineers/Veneers? Do they last? Are they expensive?

I am seriously considering one of these procedures, probably the lumineers because I'm not thrilled withe idea of grinding down healthy teeth with the veneers. There is nothing particularly wrong with my teeth other than I don't like the shape of them and I have small chips on my two front teeth.

There is nothing particularly wrong with my teeth other than I don't like the shape of them and I have small chips on my two front teeth. But I'm wondering how long they will last for because I have porcelain fillings and I was told they'll last 10 years, so is it the same for the veneers? They aren't really permanent? And will they damage the teeth under them? And about how much do they cost? Any other information or opinions you'd like to throw in about them would also be appreciated.

Thanks!
