Hello! I own a small business making custom metal jewelry. Since my business recently grew, I decided to invest in a laser cutting machine that can cut metal. I've been doing a lot of research online for something relatively small and under $20,000, but I could only find Boss laser HP 2436. Are there any other comparable machines that could cut through silver and stainless steel (possibly gold) sheets? I'm not looking for a huge surface area. Any advice would be greatly appreciated! Thank you!
