Happy to share some insight - hope it’s not too late seeing as this question was posted a while ago.
I don’t know of any good suppliers at the moment, but I do know how to find them. It’s not as complex as you might think...
If you are going to spend less than $1,000, then:
1. Search Amazon for available products and suppliers.
2. Search Google for available products and suppliers.
3. Search Thomasnet.com for available products and suppliers.
4. Ask a local convenient store owners who they use for a supplier or if you can buy equipment from the owner.
If you are going to spend more than $1,000, then you may want to consider issuing a formal Request for Quotation (RFQ). This will allow you to compare multiple bids by not only price, but other factors as well such as delivery charges, quality, customer service, etc.
