However, it also sucks that a lot of other companies tend to price-out newcomers. But that said, and I've noticed people are quick to forget in this kind of conversation: a lot of those same companies have gear for under $100 (yes, even Teenage Engineering).

Beyond a toy like that, there's also standalone music making gear that might be for fun for kids (and adults) to play with and probably won't hurt your wallet that much, specifically the Pocket Operator line of synthesizers. Source: about 1 year ago
