My DDs had it done at Pop Century in December. Each was like $20 I think, we just did the string with a bead at the bottom, lots of bead will add up. They each had one done sort of behind one ear. That way if they wore a pony tail they could leave it hanging.
One lasted for like 2 months. The other fell out, just came out completely without being pulled or caught or anything in like 8 days. We were kind of suprised, the whole thing just came out, hair and all.
