I just stumbled on Crypto-Trade at
https://crypto-trade.com while looking for an alternative to the insanity of BTCe but wanting more currency pairs than the Gox. Crypto-Trade supports BTC/USD and LTC/USD as well as the major crypto-pairs. It also has a shoutbox with a great little community inside it. Additionally, the devs and admins are very active in the shoutbox and always responsive to suggestions. There are regular redeem code giveaways and the company behind it is very open, trading on btct.com and litecoinglobal.com. Personally, I also like the rules in the shoutbox. Users are expected to act like adults. Cursing is allowed, but trolling isn't. Pretty much the exact opposite of that other exchange.
Within the past two weeks, the release of their API has made it a truly viable exchange. I've managed to satisfy all of my trades with the liquidity available. Arbitration bots are already working to balance out all of the currency pairs, and the community is growing every day. Stop by and say hai!
