Risk, costs and benefits of recutting stone? Anyone have experience?

As Dan suggested here:

I may consider having an old 4.5 carat RB recut. I''m not sure I want to do this, because it''s a family gem with sentimental value.

Are there any risks in recutting a stone? Is it expensive?

Does anyone want to share their own recut story? (with pictures?)

Thank you!
