Do you have any experience in withdrawing EUR instead?
I do. I haven't raised the limit above €1000, so I made five withdrawals (SEPA) of €1000 each. The first one took 30 days before it was in my bank account. The second one still hasn't come through even though it has been ~35 days now.
Since the bitcoin price was pretty stable for the last few months Mt Gox was a good place to get more money for each coin providing you could plan in advance. Now that the price is going up again I have registered on bitstamp, I think the bitstamp-price 30 days from now will be higher than the gox-price today.
