Last fabrication shop I worked in use had cheap worn-out DeWalt chop saws to cut-down stock and I hated them. The cut starts straight and ends crooked as hell. I got in the habit of cutting 1/8" too long and dressing it down to size with a grinder. I've had cheaper horizontal band saws in other shops and they cut alright, but something was always going wrong with the blades. I've worked in a shop that had both a band saw and a cold saw, but I didn't use either because I didn't do much fabrication back then.
For just one saw in a personal welding and light machining shop to get started, which would be the better to have until you get going? I figured a cold saw was just a beefier version of a chop saw until I started pricing them. I'm hoping the super-expense means the blade doesn't walk like a chop saw. Mainly being used for angle, bar shock, tubing, etc 3" and under.
The shop I worked at with the chop saws says the owner sold-off an Ironworker years before I worked there and talked about that machine like it was sent by the gods to them.
