I like the mini-Mendel, don’t get me wrong, but there isn’t nearly the kind of documentation for it as you would find for the full fledged Mendel.  Sure, it’s a little cheaper, but a Mendel gives you nearly four times the build area.  Since the price barrier to entry into the RepRap project just isn’t that high, the bigger issues are probably going to be quality of documentation, support, skill level required, and interest.  Is there a detailed mini-Mendel construction guide somewhere?
