I have a Kent mill that was built in 1985 sitting next to a Bridgeport series 1.
The Kent is much more rigid than the B'port. When I bought it the quill feed was not working. I tore the head apart to the bare casting. There was a broken gear that ran the quill feed and a crushed quill skirt, a sheet metal piece that keeps crud and chips out of the quill.
I did some searching on the net and found parts were available in California.
Cost for both parts was about $100, which I found to be reasonable enough.
We had some Acers at work and the guys who ran them liked them pretty well. I never ran them, so I can't say first hand.
What I seen in over 30 years of working on and around B'ports, Laguns, Hurcos, Acers and a few others is that if they are not abused, repairs are seldom needed. It is comforting to know that parts are available though.
Of all of the brands, I feel that the B'ports had the best quality.
BTW, welcome to the forum. You will find an immense amount of knowledge here.
