What's the best sled?

[Lobsterjohnson]

We're starting to get some snow around here and I really want to go sledding...but for some reason all of my family's old sleds are gone. I'm guessing they were thrown out during a cleaning of the garage, but regardless I'm in the market for a new sled and wanted to get some suggestions. Fast is obviously the most important attribute. Also, what are some good items to turn into sleds?

More often than not, the cheapy plastic ones you find at Target are great. I'm a fan of the disc sleds for pure speed, but to each their own.
