I spent $230 USD, and bought one similar to that... except it came with Tiger Woods 2004 for the PC, and connects via USB. Why, just the other day I was playing Pebble Beach.
It's not perfect, but it's pretty good. It does the same thing as the one above... the site is
www.qmotions.com.
It's a ton of fun, really... and the best part is the putting, IMO. I could putt all day with this thing.
