Personally, I barely trust MtGox w/ my BTC (i'm only there for trading because MTGOX is the market with the most liquidity).  If you're trying to cash out of BTC and you don't want to give your personal info to anyone, might i suggest SPENDING your BTC rather than converting it to fiat.  Spending them would not only let you avoid the necessity of giving up your info, it would also help the BTC community by using it for actual trade thereby reenforcing its utility as a currency.
