Draw your own conclusions here but its been my observations that sites with terrible cashout histories have the best bitcoin prices.
Personally, I dont think thats unintentional. I think that its the same bullshit as those grey poker sites that take 3 weeks to process a cashout because they know that every 5 minutes you consider cancelling it and taking it to the tables. Which generates them rake. Same principle; a lot of people waiting for 3 weeks to get their bitcoins or cash transferred are going to say fuck it at some point, cancel the withdraw/transfer, and jump back on the trading train, generating fees for the site.
BTC-E has consistently deprecated values but generally processes transfer requests within minutes. They are also rumored to be Eastern Euro crime syndicate types who decided to postpone shutting their operation down and fleecing all the wallets because its so profitable to let rubes sit there and whittle away their rolls at 2% per transaction. But they handle their biz like champs so fuck it. And on the other hand, you have the 'reputable' white knights like Gox who are so fucked up that it can be dramatically -EV to rely on their time tables for offloading currency. Such is the nature of the beast.
