Key Buying

My mom is going to get me a $30.00 key. I haven't decided whether I should get 1 key or a few cheaper keys that are under $30.00. There are some Nissan keys that I like on Amazing Keys. I also want to get a fob for a 2007 Toyota Tundra, but my mom wants me to stick to keys because keys are my thing. My mom wants me to order something from Sunshine Locksmith Team because the guy there was very nice to us.
