You can always compare it to the cost of doing a bank wire to MtGox.
Bank wire to MtGox is relatively fast and the fee is a flat rate. If you are after a large amount of BTC, then this is the way to go. But if you are just trying to pick up a few coins, unless you can find someone to meet in person and trade for CASH, there is going to be a cost of doing business.
I'm also accepting bank wire for higher amounts, and I bet it will be faster than mtgox.
