text: There are lots of possibilities, depending on your son's interests, and what you consider a "decent" price range. A small dobsonian telescope is a good starter scope at a reasonable price (~$250 - $800). Meade Lightbridge dobs are built a bit better than the entry level ones and disassemble for better portability (~$500 - $1000).\n\nFor a more high-tech, computer controlled scope, the Meade LXD75 series (~$900 - $1400) is a good place to look. Various Schmidt-Cassegrains from Meade and Celestron ($1000 - $5000 & up) are another possibility.  Astromart is a good place for used scopes, as it's used mostly by serious amateurs. Avoid eBay unless you really know what you're looking for - a lot of junk there. \n\nThe links below are a few places to browse, plus the Yahoo telescopes group where you can find some informed opinions about astronomical equipment.
