I've got the TOUR version of the Boomerang.

It comes with an 8 foot "Carnoustie" putting mat and an instructional DVD.
Great for indoor practice as mentioned on the following thread.

It sells for A$75 on the website. (go to order page and select Australia) or US$35.
Mine's in a great condition (mat hasn't been used and the boomerang return device has only been used a handful of times. Looks new) and I've still got the original box.
Sell for $25 plus shipping. That's Aussie dollars ...
