I've been using one for 30 years (intermittently). I don't use it for any sort of 'production' so it's not worn out. It is not an impressive machine but is versatile. I guess maybe it is the Bridgeport design, but I hate all the itty bitty parts in the power feed and the quill drive is a bit puny, i.e. don't go bearing down hard on large drills with it.
I recommend putting a power draw bar air motor on the top of it to facilitate tool changing. It will save you much time. I made a 4" column riser that is permanently attached, and so the draw bar bolt is pretty high up there.
Also a good DRO is key to satisfaction with any mill.
Back when I used to use a lot of HSS endmills, I needed flood coolant on the machine. The table coolant collection trough is nonexistent. I made a large drip pan to catch the incidental drips. This was fashioned to attach beneath the table elevator screw: just clamp the knee to the column, unfasten the screw base, wind the screw up and then slip the drip pan underneath and fasten it down again. So you end up with plenty of toe space beneath the pan instead of tripping over something.
