At least 90% of successful telescope purchasing is doing the research, and that means active participation by the end user. Satisfaction is in direct proportion to your interest in and knowledge of what you are looking for and at, no less than what you're looking with. As for the latter component, I recommend this sight (sic) which has some interesting links of its own -

Ultimately, a telescope is only as smart as the user. Happy hunting. :o)
