A drill press is like a lawn mower. They all will drill holes and cut grass. How well and easily they do it is what the difference in price, weight, and size determines. In a drill press, it is best to get a floor model, one with a heavy frame, multi-speed, and 1HP motor. As to the multi-speed, the ones with variable speed dials usually fail in a year or two. The ones where you change the belt position by hand will last decades. If you want the ultimate in VS, find a used unit with a motor that is shot and change the motor to 3 phase with a VFD for speed control. A 3/4HP motor will usually do the job for most knife size drilling.
In drill presses, the older and uglier/oilier/dirtier looking the better in most cases. Those old boys are simple, built like tanks, and easy to take apart and clean. I would bet that there are more 60 year old Craftsman drill presses still working than there are 10 year old Chinese imports.
