I am glad you started this thread! I am so confused by the things too. I want one..but I am not so sure I "need" one. KWIM? If I were to get one I probably would get the CB..as it is the least expensive, and has the smallest foot print. BUT, I do love some of things a Big Shot can do too ( like cut thicker materials..not sure I would ever need that feature but I like it LOL)I don't see myself using it enough for a hobby to justify the heafty price tag that comes with a lot of them. I adore the vagabond but I just don't want to pay that much for it. I do LOVE the look I see on a lot of the projects that utilize the die cuts. I personally think they can take a project..be it patterend paper or a stamped image to the next level of looking professional.
Like I said I am still on the fence about which one.
