This is the way business works:
State legal MJ growing caused a flood of people growing. This caused all kinds of equipment and supplies being sold. In business your goal is to charge as much as you can. When cell phones 1st became popular, the prices were unreal. I paid nearly a grand for a phone in the 90's few years later, better smaller phones where $39.
Not many are making bud trimmers. They are no more complex than a chainsaw, weedeater, or microwave... It's just a spinning blade and a vacuum in a drum.
It's $100 worth of parts, selling for $1500 ... that's why I'm making my own.
I'm just kinda stuck in what kind of blade to use. I can't find a supplier for spirial razor blades, so the reel blade in a lawn mower might be the answer.
