I purchased a USRC 1 pound roaster last year. I love it too. Great control, rock solid build. I thought that 1 pound would be more than I needed for my 2 - 2.5 pound per week habit. However, if you roast for anyone, you find that 1 pound is limiting. I regretted not getting a 5 pound roaster.
Well, a couple of weeks ago, I'm reading PC World and it talked about a Search All Craigs Lists site that searches all of the Craig's lists sites. I typically search for espresso machines, grinders, etc so I threw in "AMBEX." STOP THE PRESSES!!!! "AMBEX 2K Roaster with Roast Profile Plus" came up. Used only a year and half, at 1/3 the price of a new one, and within a day's driving distance.
As I told my wife, "If this is not a message directly from God, I don't know what is!" Long story short (if that's possible at this point), I now have a van load of Ambex 2K roaster waiting for me to clean out enough room in the garage, and a wife who says, "You know that you're insane, right? RIGHT?" Well, of course, I know THAT. I thought SHE knew that!
Anyway, I haven't tested it, but I'm really looking forward to giving it a whirl. It's a beautiful machine. If anyone has any profiles, tips, etc, I'd be interested in hearing them.
