I think that someone with a 500+ rating would take their e-bay account seriously and would not likely want to screw it up.  I have found that on some items it can take quite a while to get it across the border.  I had one item that took almost a month, I think everyone at the customs office had to have a look at it to see if they could figure out what it was.  Patience is the key, especially if you are dealing internationaly
