just signed to this new marketplace called TradeHill and I must say I'm liking it more than MtGox
you can sign up here:
ttp://www.tradehill.com/?r=TH-R1445it allows a zillion of different withdraw options (including Paypal!) and has just as many deposit options as MtGox
also, this new exchange is setup to trade Bitcoins against a wide array of currencies, each currency with its own independent market
