I don't think it is helpful to characterise a large Newtonian as little more than a cheap "light-bucket".
Sure, inch for inch they are inexpensive compared to many other designs but a well made, optimised Newtonian with a sensibly sized secondary mirror are exceptionally high-contrast telescopes (second only to a refractor). As a planetary instrument, I'll back a moderate f/ Newtonain against anything apart from a similar-sized refractor.
