what are your experiences with it lately? I'm considering whether to do it via gox, or transfer to bitstamp and do bank transfer from bitstamp, that would cost me 10% because I'd have to buy BTC at mtgox at higher price, transfer BTC to bitstamp, and sell there at lower price.
Don't use Gox. What country are you in?
I live in Croatia and Sweden. Gox prices are tempting but I put a lot of effort in this and can't risk payment delays or worse. Gox support was incredibly, incredibly slow when I had a trivial issue, I can't allow that with my money.
