My aunt recently bought a Cameo after her Expression died. If my Expression were to die, I'd probably do the same. She showed me some of the cuts and they were very sharp and even the tiniest details cut perfectly. I wish they had this machine a few years ago when I bought my Cricut!
I'd probably go ahead & get the extra blade & mat. Isn't it true you cannot buy supplies for the Silhouettes in local stores? I thought you had to order them online. That might save you in the long run.
