AnyCubic Kossel is a cheap delta-type 3D printer. There are two versions, i.e., pulley and linear versions. You can buy a pulley-version printer, which is cheaper, at about $200 including shipping cost. It is easy to be assembled too. It comes with a pretty printed manual with a method of installing firmware; however, unfortunately, no firmware comes with the printer. I struggled with several types of downloaded firmware and finally the printer works well with Repeater firmware. I put the updated firmware file here.
