What brands and products would be good for recording singing and maybe guitar…What all do I need?

I am thinking of recording some songs, and Maybe having a friend playing guitar in the background. I don’t know at all what I would need to record it and make CD’s with it, or even which products to buy and where to buy them. Which brands are good? What equipment do I need? Price range?

I need a lot of answers for this one I suppose.
