Dancin Dogg Golf Simulator

Looking to sell my almost new Dancing Dogg Optishot Golf Simulator. It's been opened but barely been touched/played on, and was bought a few months ago. The reason I'm selling it is because I bought the P3ProSwing today as they were having a 50% off for the first 25 customers that called in this morning.

http://www.dancindogg.com/ is the link to the site which lists everything that is included (Sensor, software, tees, etc).

Asking $300. It sells brand new from eBay or Par2Pro (Canadian distributor) for $400 plus taxes.
