Coffee beans can certainly be roasted using a regular stove or even a popcorn popper, but if you are serious about roasting your own coffee beans at home, you should probably invest in a coffee-roasting machine. You will have far better control of the temperature and other conditions.
The prices of coffee bean roasters seems to range from a low of about $70 to a high of about $595. The smallest and least expensive coffee roaster will only roast enough green coffee beans to make one 10-cup pot of coffee at a time. The most expensive coffee-roasting machine that I located would roast about nine ounces of green coffee beans at a time.
There are varying aspects of coffee-roasting machines that you will want to consider before you purchase one. For example, you will want to know just how long it will take to roast coffee beans, how many coffee beans can be roasted at a time, and how much control you will have over how long the beans are roasted. Some coffee roasting machines (the more expensive ones) will give you greater control over the coffee bean roasting process than the less expensive ones.

However, before you invest any big bucks in a coffee roasting machine, it would probably be an excellent idea to start out with the least expensive variety and work your way up.
