What are your thoughts on choosing a machinery supplier?

I’ve been in the market for some new equipment for my business, and I’m feeling a bit overwhelmed with all the options out there. I've heard from a few people that finding a reliable machinery supplier can make all the difference, but I'm not quite sure what to look for. Do you guys have any recommendations or experiences with different suppliers? Are there specific brands or companies that have treated you well, or any red flags I should watch out for? I’d love to hear your stories or tips—thanks in advance!
