What exchanges do folks use and/or recommend? I have a little bit of coin

that I'm considering changing to $$ when BTC hits $510 (LOL). just wondering what exchange seems the safest and the least expensive.
Thanks
www.coinbase.comI agree!
I'm with Coinbase as well. It took a little time to go through the approval process. Linking checking account with coinbase took a few days because I had to enter in two (2) deposits they made to "confirm" with coinbase. The same thing has to be done on other exchanges. We have to send them a copy of photo I.D. (front & back) and a copy of recent utility bill. I cannot remember everything I had to do to get confirmed with coinbase but I think it's worth it. I like the 2FA (2 factor authentication) as well. They will send you a text message with a 7 digit code for you to log in. Without that code, you cannot log in. It is done every time you log in.
Still PLENTY of time for $510.00.
