Where is the best place to buy a vending machine in Australia?

I'm looking to buy a vending machine in Australia for a small business and would like recommendations from people with real experience. There are plenty of options online, but it's hard to know which suppliers provide reliable machines and good after-sales support.

I'm interested in a machine that's easy to maintain, energy efficient, and suitable for offices or commercial spaces. If you've purchased one recently, what should I look for before making a decision?
