Hello Don,
I have the AT535SS 21" scroll saw ( plus stand ) from Axminster tools here in the UK.
I have had the saw for a couple of years now which I bought to replace an entry level 16" saw which I had been using.
I am by no means an expert on scroll saws so all I can really offer are my own experiences so far. I don't know how the saw compares to say a DeWalt or Pegas for example as I have no experience with these saws.
However, I am very happy with my AT535SS. I would say the saw has minimal vibration, is well built and quiet. The tilting table as opposed to a tilting arm is a nice feature which I prefer. The saw has the Pegas blade clamps as well which also seem of very good quality.
I do not have a foot switch but may look into getting one in the future if they are available. The after sales service from Axminster tools is also very good, I also purchased one of their belt / disc sanders and have also found it to be a reliable machine for what I need.
Sorry I cannot offer more "experienced scroll saw user " advice but I hope this helps in some way.
Regards, Alan.
