If you're an American, a sports fan, you live in Britain or Ireland and you DON'T have NASN yet, then WHAT ARE YOU THINKING?
Sure, they don't have the NFL or NBA (you need Sky Sports for that), but the amount of hockey, college football and basketball and, most importantly, major league baseball that NASN provides is tremendous. Last night they had an advertisement that informed viewers that they will be showing 250 baseball games this season! That's 250 more than you're getting now.
Sure, I'd love to be able to get every single Met game as I would at home (along with the Yankees, Braves and, possibly, the Cubs or Red Sox), but that's not possible -- YET. Someday, it will be and I can't wait. But, in the meantime, NASN is just so much better than nothing.
