I absolutely agree with Mark that a 4 inch refractor is hardly a mainstream recommendation for beginners these days, when you can get a compact 8 inch Dobsonian for very little money.
Look, there are a handful of "refractor fanatics around", and all of us like to have a refractor handy for quickly throwing out onto the verandah for a "quick look-see", but deep sky performance of even a 5 inch refractor is so modest that one soon tires of the instrument.
Mark is absolutely right that light pollution renders a four inch, even a super-high-quality four inch, completely useless for everything except viewing a small number of very bright objects.
