I have a Prusa MK4 and i really like it. Even though you would get better quality prints with the same amount of money else where, its just good enough for my needs. And i love having the peace of mind that the owner behind it really likes open source. I do not have the feeling that i get features stripped away from me or some other corpo bullshit ruining my day. Use it since 2.5 years (~5 prints/month) now never had to fix anything.
