If you don't mind used...... there are restaurant wholesalers who take over retaurants when they of business, they buy the stuff cheap, and offer at at big discounts to reselt it.
You could even call the manufacture and ask them, some times they have demo's or they may know of someone wanting to sell one as they don't use it anymore, etc etc etc...
You can ask a coffee shop or any restaurant owner, they may know of suppliers that have deals, heck they may even get it for you, and sell it to you cheaper than the regular price......
