I recently bought a nice, used Guardian online. The bow was "as described" and the price was fair.

I won't get too long winded here, but in the end it cost me as much to buy a good, stripped down, used bow ('07 model) and have set up for me as it would've to get a new one from the get-go. Plus, I don't have a warranty. Live and learn I guess.

I think it depends on how experienced you are as to whether buying online is good for "you" or not.
