Hey Wiz, without doubt the 441 clone will make the 45k look ordinary but remember that these machines were the main harness machine for the best part of 70 years! Sure, the Pearson no6 was the saddlery machine for the heavy stuff but the 45k was and still is a fine machine.
In an ideal world a 441 or a 205 clone would sit in the center of everyone's workshop but there is still room for the 45k/GA5. Every saddler I know has at least half a tonne of cast iron in his/her workshop and for the person doing lighter work I suspect we are being a bit heavy handed telling them to get rid of the older machines.
I intend no disrespect here to your experience and knowledge - which are way beyond my meager abilities - but I think we often need to consider where people are actually starting from with their own experience and needs.
