I have a Big Shot, an Expression and a Silhouette Cameo. I would keep the Cameo and the Big Shot. One thing to consider is that you can use all other company's dies in the Big Shot. My local craft stores have one of the brand name's dies on sale every week or so. I picked up 2 wonderful Spellbinders die sets yesterday for 10 bucks each. I know that Sizzix is coming out with bunches of "nesting" dies and thin dies, which are quite easy to store, and they don't take up much room. If you like to make cards or mini books, these are wonderful. Good luck!
