$100 isn't going to get you much, unfortunately. Someone else has already suggested volcas, and they're probably your best bet for that price point - the only other things you might check out are the Teenage Engineering Pocket Operators, or one of the cheaper behringer things like Crave. That said, another direction you could head is to pick up a midi keyboard, and start playing with soft-synths to get a feel for the kinds of things you want to do. If you make sure to get one with midi output (not just USB midi) it'll stay useful when you eventually buy other gear.
