Cricut Machines - does anyone have one?

[indygphib]

Hi all,

Just wanted some opinions on the Cricut die cutting machines. Jo-Ann Fabric has some pretty good online deals on them this week. Since I'm a teacher, I'm thinking about buying one for making stuff for my classroom. Even with the sale, though, the machines are still pretty pricey. So Cricut owners: would you mind giving me some feedback before I commit to buying one?

Thanks!

(Oh - and do they have Greek letter cartridges?)
