With a reputable shipping company, yes it's safe.
However, the buyer can still come up short, refuse to pay, refuse receipt, and you're out two-way shipping costs, but your item will be safe. It's not like you can get ripped off. Depends on how you write the shipping contract.
Another option is setting up an escrow account. He wires funds to escrow, you get money when he gets item. But on a $2k item the costs may be a bit prohibitive cutting into your nets sales $.
