The Hardin are very good. Even if they (or were) made by Guan Sheng Optical in Taiwan. Other companies that sell under its brand names GSO Telescopes Meade, Orion, Celestron and many other lesser-known brands include.
Check to see whether there were significant irregularities in the tube, and especially if the mirrors and exterior mirrors are in good shape. The mirror must be clean, without dust or cobwebs in the large tube. Meetings have two Teflon pads on both sides of the mounting height and six tablets or a ring of rollers. The scroll ring is better. Verify that bearing surfaces are not torn or damaged.
If the owner does not know how to get to see you, as a collimator mirror. This will do two things: to learn to show the importance of these adjustments and whether the owner knows his team to make.
How was from another poster, for the price you get the stock eyepieces (25mm and 12mm, I believe) and shape. If the scope is equipped with a Telrad device even better.
They have left the company several years ago, but the fields are good. I have never used, but it has a good word of mouth reputation in the community of amateur astronomy.
I have some information: http://www.astronomyratings.com/product/ ...

I think this area was originally is about $ 400, but 10 new "Dobson is currently $ 500 or more. Perhaps the seller does business by some to brighten the eye and accessories. If the box is in good mechanical condition, go ahead .

It took only 10 seconds with Google to find a review of this telescope. Do not mix with us.
All these areas are carried out by one of the two companies. They are all good.
They are outside the company. Its scope was good but nothing special.
