These days you practically have to keep a constant moving vessel and consistent temperature, so a barrel roaster is what most places use if you’re not a big a distributor.
You can find some cheap “less than $300” out there if you’re really hardcore about your coffee, but the quality control for the finishing and off-gassing some of these places has is way worth the cheap-ish price for a roasted bag for $10-15.

Hell, a popcorn popper can roast beans if you want to get really cheap.
You can roast in the oven as well and smaller doses in a frying pan - works well.
