Be careful when using lbc. A few weeks ago, a friend of mine carelessly sold some bitcoin to a high-reputation buyer with hundreds of transactions. Turned out that the buyer had purchased the account. My friend ended up only losing a couple hundred bucks, but it could have been much worse for her. Just make sure that there aren't huge gaps in the buyer's history. I've done over two dozen trades on localbitoins myself, ranging from $50 to $500+ in transaction sizes, and haven't had any problems myself. But better safe than sorry!
