Will depend on what you are wanting to cut, the other thing you will need to consider is where you locate it, I have one but it produces a lot of dust, has a hoover type attachment but that isn’t great so I need to make sure it is located well away from anywhere I am doing vinyl work.
If your looking to cut mainly foam & ACM then one of the blade type cutters that don’t produce dust may be a better option.
If you need something that will cut large boards then going to cheaply will mean you end up with a machine that isn’t very rigid which will affect the accuracy you can cut with.
Try a search on the forum as the question has been asked a few times & the answers you are looking for may already be here 😆
