I am starting to research the home golf simulator... but I want to be able to play courses and perhaps a virtual golf league with my buddies.

It's the best reason I've found for a man-cave and with my girls graduating college... about to have some more room in the house!

If you've done it, what did you learn that I should consider? Also, what equipment did you get (this list seems to be expanding almost daily)?

And if you've done it, is what and how you thought it would be?
