There is no straightforward answer . Why a 'bean to cup'? Buying and storing freshly roasted coffee beans can be hit and miss unless you know exactly which beans you like and how you like them roasted. What sort of coffee do you like? What constitutes a 'reasonable' amount to spend? If you want simple try a Bialetti stove top pot. Cheap tobuy and easy to use. Have a look at youtube videos. You will know straight away if you are interested and you wont have spent a penny. If you must have a machine, look at James Hoffman's videos on youtube, he tests a lot of machines. Aeropress is another cheap option, I would have a look at these as well. I wish you luck: have patience and be prepared for inevitable compromise. And remember- one person's wonderful cup of coffee is another person's disappointment.
