something i recommend is Breville/Sage/Gastroback precision brewer , it's an amazing brewer , which give you much control on different aspects of brewing, i don't think it's approved for a commercial setting ( someone can check and correct me if i'm wrong ) but due to it's capacity it can be used for a very large household or a low volume cafe' ... it's just a good machine all around , it is SCAA rated and also you can purchase a adapter for pour over , it's about 300$ in US , but it is extremely worth it ( you can get it with glass carafe for less , but don't do that , thermal carafe is way way better ) . i know it's a little bit over your budget , but you get the best quality for what you're paying for .
