Glad we're having some discussion on the DIY 002. Is anyone interested in reading Sonny's blog? He would fit right in on this forum, with all the tinkering around he and his friends are doing.
When I was there a friend had a fluid bed hack under his roaster for an experiment. That's why I gave him a plug here; nothing to gain for me, don't own one or looking to buy.
I've seen it in person, and it's on a different level than a Huky (which I've owned since 2013). A base Huky is a great deal, but if you buy every conceivable option it's gets pricy. A complete machine is well, complete. Chinese Roaster are much less expensive than Taiwanese roasters, that's a different discussion. So yeah you can get a 300-500g Chinese roaster for about what a Huky with accessories goes for.
I've never had my Huky apart, but I can report it's a cinch to take the 002 down and re-assemble. If your the kind of person who likes to mod that's a big plus. It's still a home/hobbyist/experimentor's machine, not designed for continuous use. That's basically where I draw the line between hobby and pro coffee roasters.
The appeal is kind of limited, and if someone is an owner chances are continued involvement with the builder is possible. Just a guess, I've had no problems communicating.
I requested a price quote as well. Mine came in at $1800 USD and is current as of about 2 weeks ago. Shipping to Hawaii from Taiwan was quoted at $181. They also charged a bank processing fee of $35. I ended up buying a Kaldi Wide, about $525 from the evil bay. The pictures of the DIY looked like it was a nice product; but the Kaldi at about 1/4 the cost is so far turning out pretty nice. Quality is excellent. I just got my TCs in the mail and about to try my hand at drum roasting this weekend...
