No contest for me.
Kev bought me this for Valentines day years ago
and a few dies and embossing folders later, I use it almost every time I craft. You can tell I've had it a while, as it's the first blue model that Ellison released.
And I crafted with my Big Shot today, making this LO using loads of old stash,
this page, but I used a sketch I found on the October afternoon site.
So, which craft tool can you not live without?
