Cricut v.s. Pazzles v.s. Wishblade

I really want the Wishblade it is very expensive but I like the fact that I don't have to buy cartridges for it. I can use my own fonts and some of my own designs. I am trying very hard to convince my husband that I really do need this $500 investment for my business I guess we will see if he bites my hook. LOL!
