Hi, I use Igus polymer bearings. I also own some quality SFK linear ball bearings ($12/each, one of the best equivalent of the chinese LM8UU). The SFK are great, but the polymer bearings are less expensive, more quiet, and works just fine. I don't know what brand Lulzbot resells, but the Igus can be bought directly on their website.
