Plucking is best for now, but you want to laser zap them before they turn gray. Once they're gray, they can't be zapped and you'll look like a cat when you're too old and senile to pluck. I recommend the Tria. Yes, it's $500, but if it takes more than one zap at professional laser place (and it could take 6 or 7 appointments to get it totally gone), you'll spend way more having someone else do it. With your own you can zap those 'til they're gone and any future hairs too.
If you let them grow, shave them, and then zap them, and they're really black, they'll be way lighter and thinner in three zaps and gone for good in 5 or 6 or so.
