Does anybody have a favorite coffee roaster? I am looking for one for my BF's birthday, without spending 300 bucks. He loves a dark brew, and the review of the Nesco Home Coffee Roaster ($150) on sweetmarias.com indicated this was best for lighter roasts. Is the cheaper FreshRoast Plus8 ($75) any good? The pricier Hearthware i-Roast 2 ($180) worth it? I'd love to hear what you coffee afficianados think.
