Smallish 1/2 cup capacity
No control over roast profile
With this machine on the market, there's no excuse for not roasting your own beans. Dump in a half cup of green beans. Fire up the machine and keep an ear out for the sound of cracking beans. Hit the 'cool' button when you've reached your desired roast.
I don't take advantage of the timer dial, instead opting to just manually end my roasts. If you took the time to work out the dial setting for each of your bean varieties, though, this would literally be a 'set-and-forget' process.
Now that I've gotten a number of roasts under my belt, I wish that the roast profile could be manipulated on the Precision. This is a minor quibble, though, and a machine with that sort of flexibility would certainly cost considerably more than the Precision.
For the $105 (delivered) that I paid for the Precision, it will pay for itself in no time. Go get one of these!
