It's called a Bocaboca, South Korean brand (home roasting seems to a big thing over there, the little Nuvo Eco handheld roaster I got before was also from South Korea). Bought mine through eBay but you can read a decent write-up of it here: https://dailygradient.com/first-coffee-roasts/
That's the 250 model (recommended max capacity is 250g), they also do a 500g but I figured that'd be a bit big for my needs. I do 3-4 200g batches once per fortnight. Means I have a decent variety for both filter & espresso and I can get 4 batches done within an hour (roasted, cooled & packed).
Like I said, I'm not exactly going to be giving Steve here a run for his money, but it's quite a nice little thing to work with (Though I definitely had a few under-roasted batches when I was getting my eye in so to speak. Was basically like drinking grassy water...).
I reckon a Kaldi Wide might be a better option but the Bocaboca is a fair bit less fuss, as the Kaldi needs to be placed on a gas burner and also has no cooling function. However, it does have a proper thermocouple which would definitely be a nice to have.
I haven't had professionally roasted beans in almost a year now (though I got a small back of locally roasted stuff at xmas which was honestly no better than my own) and I'm terrified to go back. Though my little roaster has now paid for itself in money saved buying green coffee, so I can treat myself now and then to some proper stuff without guilt.
