Hmm...why use the power tools at all, and pay something to Alibaba or Proxxon? We can cut with hand tools and gain muscles. It doesn't really matter how many models you will make, as long as it makes the job easier, IMHO. Everyone should be using the tools of their choice.Goodness - how many models do you have under construction at the same time to need machine help for the yards....
Like Y.T., I do the same. Saves power, requires dexterity, and gives the soul a sense of accomplishment. This thing only brings something to Alibaba. Money.
