I'm so out of the loop. I've never even heard of Grand Caliber.
I got a Big Shot last year when Sizzix clearenced their Hello Kitty model for $50.
I'd LOVE to see a must-have die thread, with examples.
I recently got my Silhouette up and running again and the one thing that has been driving me batty is not seeing the files in use and exampled. (ANd I have a HUGE gift card to use there too--that was such a pleasent surprise.)
