    We had a massive Tree mill at work, looked like a Bridgeport on steroids

    Webb, Sharp, Kent and Summit are all good machines as well.

    Correct on all points. I have a Taiwanese 3VH Webb Mill. It has the features you mention, including the extra motor bearing, 3 hp induction motor, Box Ways, central oiling and weighs in according to the literature at 3,500 pounds. According to the people at Webb where I got my parts when I was refurbishing it, they use the Meehanite cast iron process for all of the castings. It's a 10 X 54 size. I use a Chinese X servo on the X axis that I bought from CDCO and I also have a 2 Axis Mitutoyo KA DRO with a Mitutoyo scale on the Z Axis. It was formerly a CNC machine and I converted it back to manual so I kept the ball screws. There is almost no backlash on either axis.

    Webb is still very much in business and stock all of the parts for the machines that they sell.

    Plus one on the Acer.
    If I was ever to lose my Bridgeport , I would opt for a Acer . Their scraping skill level is higher than the average apple

    The Acer E-mill shown by H380 is one of the best ones out there. Sometimes a used one will be under $6000.

    All three of my Laguns have Dovetail ways. Never even heard of one with box ways. They are about 500-1000 lbs heavier than a BP depending on model and in my opinion more robust. The design of the high low selection on the head is better as well.

    I think this is what most China makers copied.

    Any tips on detecting excessive wear on box ways vs. dovetail?
    Never seen one in person actually.

    H380, that's a great price on a very good machine IMHO.

    Surprisingly a bit tough around here with clapped out going for up to $3-4k and refurbs at $9k-ish on up.
    I decided to spring for new when I bought my BP clone (made in China and claimed to be 2223 lbs)...and it just struck me that it's getting to be almost 20 years old now! Back than it was $8,100 including taxes. I figured that was just a few years of what some people spend on cigarettes with nothing to show for it.

For what a new Bridgeport cost ($15K to $17K) you can get a 5hp, #40 spindle, DRO, 50x10 table and 3 way power feed and still have money left over. Like others said they are a different class of machine.
