I have an Axomat (can't remember which model) that I bought in much the same circumstances - in its original packing, not new but not far off. I do by necessity have another enlarger for 6 x 6, and use a Nikon or Minolta lens in the Axomat (depending how the mood takes me) but I can honestly say that I can find nothing about it worthy of complaint. You could pay a lot more money for an enlarger with a more highly regarded name, but that wouldn't guarantee your son better prints!
