Should I Buy a Crock Pot: Update

So at Target today I saw that the 3-gallon crock pot is really only like $20! The 5.5 gallon is $50. I don't get that price break, but whatever. For $20, I feel like I can splurge. What does a single gal like me need to make 5 gallons of? Whatever it is, I'd get sick of it after 2 seconds, and I don't have that kind of freezer space. So I think I'm getting the cute red $20 one that matches my kitchen. I am now accepting vegetarian crock pot recipes.
