Pete123 I'm going to do a little more research, however, you have a point about the utility of the features on the higher priced model. When I bought my current Hottop more than 10 years ago I got the programmable model which I believe was only about $100 more than the basic model coming in around $600. The price has increased a lot since then but the thing is, I never used the programming features, I ran it in basic mode and roasted by sight and sound, mainly sound. When it got to where I wanted it I dumped the beans and that was it. Some beans I'd take closer to second crack but I rarely went to or past second crack unless I was doing an espresso roast. If I can see a clear connection between the ability to manipulate the fan speed, temperature and so forth and the quality of my roast I'd probably go for it. The extra $500 could pay for the refurbishment of the older one though.
I agree with you as to local roasters, its hit and miss. There's more to roasting coffee than just growing a hipster beard and putting a grommet in your earlobe. You have to respect the bean and make sure you do right by it. When you look at the journey that coffee beans undergo from growing to picking, processing shipping and roasting and the fact that a great bean can be ruined at any point along that journey, its a wonder that we can even get a decent cup of coffee. So if you get some green beans its up to you to do your utmost to achieve their potential and if you ruin it, well then you're just a jerk. And if you then sell those ruined beans as "artisanal" locally roasted coffee, you're worse than a jerk. Although if you sell them in a cool bag with a funky logo on it then its ok right?
So here is where I'm at - part of me says, you never used the advanced features on your old hot top so what are the odds you'll use them on a new one? And the savings can pay for refurb the old machine. The other part of me says - you know you haven't been maximizing the potential of the beans you've been roasting so stop disrespecting the bean and do right by them and take your roasting to the next level.
It would be nice if I had a coffee Yoda Jedi Master that I could consult. I've been doing this coffee roasting thing alone for the past 20+ years. I've not found any useful forums, although to be fair I haven't looked in a long time so maybe some have popped up since then. I've read articles and books and done a lot of trial and error. Maybe its time I got serious about it.
Its funny, when I first started roasting I was happy to share my beans with family and friends. As I got better at it I became a little more discriminating as to who was worthy of my coffee and eventually got to the point where virtually nobody is worthy of my best beans. They want the whole pound ground before you give it to them, they never clean their brewing equipment, they adulterate it with sugar and "whitener" and otherwise screw everything up and then you hear through a third party that they don't think your coffee is all that great. No **** Sherlock, no beans for you! I'm not saying that other people should or shouldn't do anything differently, its their life and they can live it how they want and if bad coffee makes them happy who am I to judge them? This is what I do and what I like and it makes me happy and I'm certainly not going to waste my time and good beans on people who won't appreciate it.
