Semper Fi CoffeeMD! I started off with a 3kg US Roaster and it has made me money. Still does. If you purchased a new roaster, Mahlkonig grinder and a Fetco brewer you would be looking at 15K. That is what I started with and have grown since. Started with just the roaster and selling whole beans. Then customers asked if I could grind for them, so I purchased a grinder. Then customers who wanted to purchase larger quantities wanted to taste so I purchased the Fetco Brewer. If you produce a good roast, the beans alone will pay for ll of your needed equipment. Others will disagree with what I posted but it worked for me.
