I've been looking into getting a Hudy comm lathe and have decided to get the Tech comm lathe (really would like to have that executive one though, but its too pricy

). I have one questions that Hudy does not have the answer to on their website. For each given model comm lathe, there are two different types of it. One has Ball Bearing guides, and the other has Hardend Steel V guides. Which one would be better? I would figure that the bearings would be best, but I want to make sure there is nothing that I am missing. Thank you in advance.
