As we know there is no one “One scope does it all” answer, and indeed the OP may be disappointed by a dobsonian scope if it doesn’t perform well to meet his/her goals.
Without putting words in Michaels mouth, I think he merely means to suggest that what type of telescope one purchases should be an informed decision based on what a particular observers goals are, and how different telescope types meet those goals. For example OP might be interested primarily in viewing solar system objects, where a long focal length, high focal ratio, high magnification scope such as perhaps an SCT might be better suited to the OPs tastes. As we know there is no one “One scope does it all” answer, and indeed the OP may be disappointed by a dobsonian scope if it doesn’t perform well to meet his/her goals. So knowing what each scope excels at, and is capable of is an important first step in the decision making process. I know personally that making choices based off of budget alone has led to disappointment over the years in many different hobbies.
