A lot of the best heat press machines in our guide are from Cricut. That's because they make excellent heat press machines with controls that work on all types of materials. If you're pressing from textiles you've printed from your Cricut machine, it makes a lot of sense to use a heat press machine that's designed to work with the same materials.
However, these models are more suited to small-scale operations, and if you're starting a small business it may be wise to pick something with hands-free levers so you don't need to apply any pressure yourself as you work to print t-shirts and hats.
Think about the size you need for your intended products and work from there. It is easy enough to pick up large heat press machines, but they won't be easy to store and you will need a dedicated space to work with them.
