Remus, There are a number of online green bean co-ops, although I am reluctant to list their sites pending Admin's ok! Green beans can cost from about $5/kg up to $15/kg, depending on the bean. With the popcorn popper, it takes me about 1.5 hrs to roast about 500 grams. I tend to limit my roasts to about 80 grams each and blend after I have roasted my beans (I also often keep, unblended, a 'feature' bean to try single origin espressos - the last one was a great Guatemalan Antigua). The reason I home roast is for the fun, control and variability of it all. I don't rate cost or quality of the end product as reasons to home roast - how can a $20 popper outperform a $10,000 10kg roaster used by a professional? In terms of cost - if I was to put a dollar value of the 1.5 hours I spend on a Sat morning roasting, it would more than make up for the actual cost saving of the beans. I would encourage you to give it a go, if nothing more than to satisfy curiousity. Then, of course, you will need to grow, harvest and process your green beans! Patrick
