I've held off commenting because all the advice you've been given is good and I don't have much to add except to saw that having owned quite a few grinders the Rocky/Gaggia 50mm grinders can stand up next to commercial grinders for shot quality. Consistency.... No.... but in the home situation they are more than adequate. Adequate being the lower end conical burr grinders and I've owned a few of them and they are fine also. It all comes down to learning the idiosyncrasies of ya gear and establishing a basic routine that allows you to get the best shot you can for minimal effort. You aren't doing 300 shots a day in a busy cafe so your options star at $150 and you can take comfort that that minimum spend will yield great results. If it were me I would be asking BF how noisy his unit for sale is (because that matters in my house) and I would like it because you know it works, you know it's been looked after, small footprint, nice bling and a price that allows an upgrade later secure that you can recoup some of ya money on it or set it ti decaf duties. Also, ya know where he lives... :pan. That's what I'd do. Over the years I've bought one grinder from Alan Frew, two from Merlos, one from a fly-by-night appliance store, one from eBay and had several come and go via trades/gifts etc. They have all been good enough for my most excellent apple colour guessing palate :rofl: they ALL have idiosyncrasies. Good luck mate but ya really can't go wrong 'fit for purpose'-wise.
