Wow Hank - amazing review. This is very interesting and I appreciate 
the criticisms and comments of a long-time roaster. You are 
definitely the right type of person for Quest M3 ownership. I see the 
controlibility as an asset in the hands of someone like you, but a 
liability in the hands of someone who hasn't been through a few 
stages of home roasting. Learning the relationship between air speed 
and heat settings in the Quest is like driving a fickle manual 
transmission car, and for someone used to an automatic it could be a 
real challenge. My Quest roasting habits have tended toward a stable 
heat setting and using air to shape the roast profile more. As far as 
drum roasters, I don't think we can compare the Behmor to the Quest 
or the Hottop. I too was dubious of the open wire drum, but it is 
really a radiant roaster. The fact that pro shop roasters are not 
like this doesnt mean it is a bad thing (not saying that you imply 
that, just riffing on this topic). It's just different. The issue 
with control though is key. The ability to slow a roast down is a 
great tool, a professional-level tool. The need to cool outside of 
the heat chamber is definitely an issue with home roasters, Behmor 

By the way, I actually like the results from 1/2 Lb in the Quest, 
even though it's not the spec for this roaster. Also, watch for beans 
in the tube between the front and back, as well as chaff that gets in 
between the drum and the outer drum cover.

One of my goals for the Quest M3 is to get it into the field, to be 
used at regional or farm-level cupping labs. The more they cup small 
batches at the wet mills, the more they start to understand the 
variations in quality in coffee processing, and making improvements. 
The Quest is simple enough to use, could be easy to repair in places 
without access to proprietary parts, and I think it works under a 
range of conditions too (low voltage etc).  I wish it was less 
expensive, but seeing as they are completely hand built one at a 
time, the price makes sense too. I hope it measures up to your 
expectations! Keep us posted.

PS: I am going to paste this into the Quest thread on the forum too.

>Over this time I have roasted from 1/2 pound a week up to 5 pounds a

>So, what about the know issues with the quest?   Roast load size and

>Lastly, will my opinions about the solid drum vs the mesh drum become

>By Christmas I should have run enough coffee through this baby to

>Behmor are welcome comments.
>But, after 2 roast to different degrees of doneness I really like the

>was able to get the magical 3 minutes between cracks to allow the
>flavors to develop fully on my first try.  Time will tell if the
>coffee is as good as I expect it to taste, but I never hit more than
>45 seconds with the Behmor roasting this bean.
>More to come.
