Well, not that realistic, but I ended up paying 0.51 which is fine with me. Bitcoin arrived on my Mt Gox account nicely so everything went well

When did you manage to get that rate? I've only been looking at the site for a couple of days, but it looks like I missed my shot. 0.62+ now.
Well.. Just placed the order, looked again a few hours later and it was hit. When I placed the order, the current rate was 0.72, so I didn't have much confidence it would get hit.
