A dry ice machine may be purchased from the retailer Amazon as a new product. Auction site eBay offers multiple products that are both new and used. Buying directly from a manufacturer, such as Cold Jet, is also a possibility.
If purchasing a dry ice machine from an online store, such as Amazon, there is the added bonus of being able to view multiple products. Also, this website has product review pages, on which the purchaser can compare the items in everyday use by other people, providing a better idea of which item to buy. Auction site eBay also provides multiple items for sale, but some may be new and some may be used. Depending on the needs of the shopper, a used machine may work just as well as new, but for considerably less money.
The purchase of a dry ice machine directly from a company, such as Cold Jet, may offer the biggest selection of machines. This company manufactures several different varieties of this type of machine. They also offer mechanical services in order to keep the machine in good working condition. Also, Cold Jet allows customers to rent a dry ice machine, when purchasing one is impractical.
