Future geek on a budget here
Should I even bother making a purchase on a reflector telescope if my budget was around $ 500? Could you legitimately get a decent one for that price? Or do you have to start dippin into the thousand dollar range in order to get your moneys worth?

Why isn't "equatorials" mentioned? Because it's a mount? Then What is "Dobsonians" doing there? It's a Newtonian reflector on a alt-az mount.
