What with Trade Hill closing and this instance those unaware should check out Intersango.com.
We don't advertise much but we are one of the biggest exchanges. We are the 2nd longest running exchange. The longest running exchange not to have been compromised. We have never suffered a hack and we are the only bitcoin exchange owned and operated by core bitcoin developers. We have the most competitive rates especially once considering transfer costs to and from Intersango.com
We operate with honesty, and have absolutely no hidden fees. Our long history confirms this time and time again.
We also have always had excellent and fast support!
EDIT: I mention this mostly due to the fact that Patrick Strateman (known on these forums and IRC as phantomcircuit) has repeatedly found security vulnerabilities like the above mentioned. Having strong developers and security specialists does make a huge difference. The whole reason we created Intersango was because we realized this was Bitcoins biggest problem, reliable exchanges.
Is this new wave of regulations affecting you? Do you still accept Dwolla and Paxum for deposits and withdrawals? It seems like those put an end to Tradehill. I would like an alternative to gox.
On topic segment: BTC-E seems to have suffered from the same stupidity as Bitscalper. Does no one understand even simple salted MD5? LOL
even salted md5's can easily be cracked
I think the min standard nowadays is using SHA 256 with atleast a 16 byte random salt
