I own one of the BrewDemon 2.5 gal conical fermentors. Came with a kit. It’s nice. I have extended the legs and put a dump valve on but haven’t used it since I was still using extract.
At $40 it’s not exactly a steal buts it’s durable, they offer replacement parts that are always in stock and the customer service is fantastic.
I use SS Brew Buckets. I really like them - drops yeast/trub into cone below the spigot. Easy to transfer clean beer. Easy to save and harvest yeast. Love the durability of stainless. Easy to clean. Would prefer a little better access for spigot cleaning… but it is manageable (and I boil my spigots from time to time just in case). Never had a problem in 2 years.
That said - the exact same things can all be done with a normal bottling bucket (or spieled type fermenter). I still use bottling buckets a lot when my SS Buckets are full.
