I'd like to learn more about that Solus, can you recommend any source for bean, roasters, etc...?
Start at Sweet Maria's.
Lots of great reviews, how to videos, tips and pointers, gear and an education in coffee, coffee roasting and coffee appreciation.
http://www.sweetmarias.com/index.phpThe roasting gear I use is no longer in production. I have 2 I-Roast model 1 roasters and they are getting old. I have seen some I-Roast stuff on Amazon, but prices are getting high.
You can see some pictures of the I-Roast here

Found some advice on a coffee forum in the UK. Guy said he is using a heat gun and dog bow. He said he got the heat gun from Harbor Freight. I am guessing the dog bowl is a steel water bowl.
I checked on that gear. Harbor Freight has a heat gun for $15 that has enough heat. For the darker roasts you need to get the beans to 470F. You might never use this...it is a French Roast and at that level of roast some of the qualities of the coffee are lost...but get a gun that will handle it just in case. Above 470F, you will have charred beans.
I have found stainless dog bows for under $10.
You will need a coffee grinder. Blade grinders can be cheap, but they "shave" the beans and the oils are then released to early in the roast cycle. A good burr grinder is better, but costs more.
So you can get your feet wet pretty cheap. Or you can go the expensive route and spend over $500 on gear. You get bigger batches and more automation....with the heat gun, you will be stirring the coffee yourself and controlling the heat.
You might want to get a temperature probe to help keep an eye on the progress of the beans. I have one, but seldom use it any more since I have a good "feel" for where I am by the color of the beans. Sweet Maria's has pictures of the beans in the different stages of roast and you should use them.
There might be other issues with the gun and bowl set up. Chaff is one. Depending on the green bean and how it was processed, there might be much flaky "skin" produced in roasting and the gun might blow it about...I'll know more when I try it.
Sweet Maria's talks about using a hot air popcorn popper. It does work but you have way to little control over the roast process and it is a mess with chaff and beans getting blown out of the popper...when I was using it, I put it in a big card board box to try to contain it all. It worked, but it was a pain. Beans blown out did not get roasted and the roast was uneven...not all beans were roasted to the same degree.
If you want, you can start with a frying pan and your stove top..I've not tried it, but I'd guess stirring would be more important since the heat is only from the bottom.
Home roasted coffee might not be cheaper with the gear you might buy....sort of like reloading....but the quality will be better when you learn what you like and how to produce it....again like reloading.
Here are some "timelines" on where a degradation of the flavor and quality of the coffee will occur:
Brewed coffee should be consumed within an hour or so after brewing. (brew to a carafe and not on a "keep warm" plate)
Ground coffee should be used within a few hours. (I grind my roasted beans just before I put them into the brewer)
Roasted coffee should be used within a week of the completion of the roast. let it sit a day to "off gas" in a one way vent container
Green coffee is good if stored dry for several years. They say that after two years the taste will change, but it will not be a degradation...just different. I doubt I'll ever keep green beans that long.
be glad to answer any questions you might have.
Good luck and enjoy.
