For a primary workhorse drill press in a typical woodworking shop, most any stationary upright drill press of respectable manufacture in the working depth range between 15-17" with a 3/4HP motor, a broad range of selectable speeds from as low as a hundred or so RPM up to several thousand RPM with a quality 1/2" to 5/8" Jacobson chuck will serve you well pretty much no matter who makes it. Depending on the work you do, you may rule in or out some models based upon the maximum quill travel (drilling depth) -- I opted for a (Steel City) model with 6-1/8" quill travel so that I can drill deep holes in a single pass, but many drill presses have far more limited quill travel (some models have less than 3").
If you are mechanically inclined and don't mind possibly repairing tools then used can be a great way to go, particularly if replacement parts are still readily available. Drill presses are relatively simple tools, so as long as no irreplaceable parts are damaged there usually is not a whole lot to go wrong unless it was poorly maintained and inadequately lubricated.
But there are also a lot of respectable choices on the new market from Powermatic, Jet, Steel City, Grizzly, and similar manufacturers. Much of the price variation between models relates to improved features and, especially in the case of Powermatic, initial fit and finish quality which can vary considerably between the economy lines and the premium models.
