While I have several Delta tools and like them very much, I am disturbed by all of the negative press they have received since selling the business to an Asian enterprise (please don't read this as Asian bashing.....not intended......the Delta business model has changed, hence the name means little now) Many people have found replacement parts have been made obsolescent and unavailable. This has been going on for over a year and seems to be getting worse.
I would not buy a new or used Delta tool any longer for that reason alone. I also have several Jet tools and parts are readily available, service has been infrequent, but excellent when needed. I have not heard anything negative about Rikon for that matter, just positive comments. Just my $0.02.
