Dude. If you want to use it don't think. Just do. If you think about not using it and its "cost" you're going to end up hating the thing. I went through that a bit when I realised I didn't want to cook mains in it most of the time. Now I'm cool with that.

So please. Make a list of groceries for one recipe and give it a go. You won't get better at this if you don't try.
