Need help with a repair project

sammydog01 thought this was worth mentioning said

OK, tech people, I bought a Waring snow cone maker from our friends at Morningsave. It came without an on/off switch. The folks at Waring say I have to ship it at my cost to them for repair- about $16. I paid $24 for it. So my question is, what are my chances of repairing this thing cheaply myself? Once I take it apart, I'm pretty sure there goes my warranty. It sounds simple, but maybe not. Thoughts?
