Ahhh, the Silhouette. Yes, I've seen of it. There are actually several threads on here discussing it. Just search for those & you can see the comparison to the Cricut.
I have a Silhouette, bought it rather than a Cricut because you do not need the cartridges. Have had a blast making cupcake wrappers, cookie bag toppers and used it to cut icing sheets. Have not had time to work with gumpaste, but it is on my list of things to try.
I really like it, there are hundreds of files to use, some free some that cost a little. You can also make your own files, and/or convert Cricut files. Need to find time to work on that also.
I love the print and cut feature. I print eis on my edible image printer, then cut with the Silhouette.
It made my Christmas cookie gifts a lot of fun.
