The only thing DS wants for Christmas is this marble run for doing marble races on. He was on a chat forum about Jelle's marble runs and someone linked to the run, which was on a special offer at the time.
Now we can't find the link in the chat, nor whichever site it was that sold the run.
I was just wondering if anyone else had any ideas. I've seen the MN hive mind do extraordinary work tracking things down when you don't have enough key words to Google!
