I actually just bought the Pizza attachment from Amazon Germany last week. I have been wanting one since I first saw it a couple years ago. It ended up being a pretty reasonable price. My wife was going to order one for me for Father's Day but the exchange rate is decent right now and there are indications that it will get a lot less favorable over the next few months.
I was really amazed how fast it arrived. I ordered it on Saturday night and it arrived on Wednesday. I was going to start a post about it but I haven't had a chance to take any photos yet.
