Hi guys,

I was going through the Coffee Lover thread and I realized not much of discussion on roasting coffee. Occasionally some sifu would talk about roasting but conversation would somehow sidetracked to other aspects of coffee. I am starting this thread so that we can discuss in depth with regards to coffee roasting. 

Any home/micro roasters sifu in the club? Would like to ask opinion on choice of roasting machine. I'm currently roasting with popcorn popper but think is time to take the plunge and get a proper machine.

I have short-listed three machines

1. Aillio Bullet R1

[attachmentid=8929604]

Pros:
- Looks. Really nice looking and small form factor
- All electric. Can use anywhere
- 1 kg capacity. Just nice for sample roasting and even small scale production
- Fully interactive with software for roast profiling

Cons:
- Expensive. 2624 USD
- New product. Just passed early release. Sorted out main problems but basically still a new product. No expert reviews yet

2. Hottop KN-8828B-2K+

[attachmentid=8929606]

Pros:
- Small form factor
- All electric
- Uses software as well for profiling
-Reliable, established brand
- Cheaper 1600USD

Cons
- Only 300g capacity

3 Sonofresco 600g/1.2kg roasters

[attachmentid=8929608]

Pros
- Simple operation.
- Easy maintenance. Only one moving part which is the fan. Since warranty would be difficult for import item, this is a plus point
- ?Air roaster (maybe cons to some people who prefer drum-roasting)
- Cheaper cost of running. Uses gas - just connect to cooking gas tank and electric for the fan
- Essentially a commercial machine, built to last
- Large capacity

Cons
- Large form factor. the 600g version is smaller but of course less capacity
- Expensive 600g 2595usd and 1.2kg 3595 usd
- Software need to add another 750 usd and also less robust compared to previous two.
Any sifus here have experience with these machines? Would really appreciate if can provide input. Of course there are other more professional sampler roasters options such as Quest M3, Huky 500, North Roasters but those are too big/bulky and the Wife says nono cos its ugly. Haha.

It will be great if can discuss on roasting experience and profiles here, too
