@LabGuy if you really like coffee and have the space to roast and a little spare time every few weeks then I feel confident that you will find it a positive experience. You can do your own math as to how long it will take for a given roaster to "pay for itself" and break even on the purchase, but beyond the bare economics you get to experiment with different origins and different roast levels while enjoying freshly roasted beans which can be difficult to find. So you may be able to justify it on both an purely economic level as well as the "priceless" experiential level.
Behmor roasting is pretty easy in that I can start a roast and walk away for 12-14 minutes and go do something else without paying attention to it; like unloading the dishwasher, putting away the clothes, starting laundry, etc. Any short but mindless task that does not distract too much from the roasting process. I have had one small chaff fire in mine due to inattention but it did not get out of hand. Beside the fire hazard it is essential to be next to the roaster as it enters 1st crack in order for you to target the final roast level.
Thanks for the encouragement. DW and I plan to order a roaster next month so I will probably be hitting up this forum a lot in the future.
