Steel City is generally considered a decent brand of power tools, they're around $600 new from what I can find online. However, I believe they are mainly sold to woodworkers so find out if this one has slow enough speeds for drilling metal, if that's your plan.
Looks very much like it came from the same place Delta 17-900's were built. I have one and I paid less than that new. They are kind of medium duty, but good enough for a home shop. Lowest speed is almost slow enough.
