"If you’re looking for the most bang-for-your-buck then you might not have to look any further than the LulzBot TAZ 4. Seriously, for just a little over $2,000, this printer seems to have everything most 3D printing enthusiasts want: a huge print area, an open-source platform, a very competitive price, the ability to print in a variety of different filaments, and good print resolutions."
