I've done it and posted on here about it before.

I have a small area at the nape of my neck that refuses to curl, so I had that area spot permed. I LOVED the results.

Its probably been a year now since I had it done and all of it hasn't grown out so that area is still behaving.

Given it involves such a small area of hair on my head I would do it again without hesitation.
