Hi Luci...right now I just use one-my Big Kick. I LOVE it-because it is so simple and fast. I do use dies from different companies-I have not had a die that couldn't work with this machine. The only problem I have had is if I want to cut thicker papers-they don't usually work well with the thin metal dies. A few days ago I tried to cut through clear acetate with a wafer thin die, and it couldn't make a perfect clean cut;-(.
