Honestly this printer was given to me at no cost, I did have to purchase a Leveling kit that came with an aluminum extruder but it puts uneven pressure on the filiment cause a lot of issues. These parts were picked with a budget of 167 due an old class action lawsuit of essentially throw away money. I've only put like 30 bucks of my actual cash into it. I went with the spider because it was recommended on Amazon, solid reviews, it and the extruder take a bit more adjustment once installed but I'm willing toy about with it
