The first cupcake maker I found was at walmart. It's by Girl Gourmet and is featured online as a bundle package because it comes with a ice cream sandwich maker also. And it's listed for only $30 for both. (Currently its sold out online. But I am sure you may find it on another website or store.
I also found an electric mini cupcake maker. Its manufactured by Smart Planet and claims to make six cupcakes in just five minutes! Not bad. It's listed for $17 on some websites on line. If you take a few minutes and google it you can probably find it for less. Target and Walmart don't have this one. But I hope they get them soon. I want one!
