I'm a Electronics type getting into this machining stuff and am working on filling my shop with cutting toys. The chop saw I've got is wearing out and am looking at bandsaws when someone mentioned cold saws. Old industrial stuff I see on EBAY looks good but I don't know anything about them except they cut fast and nice. Do you have to use coolant? I mainly need it for steel. Any recommendations?

Coolant yes,they do cut extremely nice,but most aren't really that fast.Also be aware that there are coldsaws for steel,stainless etc.and there are cold saws made specificly for aluminum and brass.Sometimes they are descibed as coldsaws but are really extrusion saws meaning the blade speed is much higher and should not be used for steel and stainless.
If you are using it mainly for steel a bandsaw is hard to beat.For one thing the blades are much cheaper to replace,so if you are unfortunate enough to cut something too hard you will only wreck a $10-25 bandsaw blade instead of a $100-300 coldsaw blade.
But if you are only going to be cutting fresh virgin stock of a known origin and hardness then a coldsaw is great as it gives you the capability to make perfect repeatable cuts to an accurate length without the need to out of nessicity mill square.
