Can I jump in here and tell you about my Cuttlebug? I really like it, and it allows me to use my sizzix dies, spellbinder stuff, and of course all the cuttlebug stuff. Plus, it was only $55 on sale! You can use the sizzix on the smaller dies but you need a magnetic adapter piece that was very difficult to find! I ended up having to get one off ebay. And while I like the dies, alphabets included, I LOVE the embossing folders, which I don't believe you can do with any of the digital machines.
I'd like to eventually get a digital one too, but I wouldn't give up my manual one for all the tea in China! If price and portability are an issue, check out the Cuttlebug.
To go further off-topic, I found the Silhouette on sale online for $111, which seemed like a great deal. And it doesn't need cartridges. Do any of you recommend this one?
