Tons of Cuttlebug examples in the galleries, and tons of threads. Wanted to buy one myself today at Michael's, but the cashier would not take my 40% coupon, so I walked away.
I have heard nothing but positive over there. The single dies/embossing plates run $5.99 - $12.99 at my Michael's. it is the alpha sets that are $59.00. Cricut is more versatile as you can change the size of the font, but the machine itself is 2-3X the cost of the cuttlebug.
