Dear Peter,
Thank you for your post.
I recently sold my unit from my personal collection -
http://www.iceinspace.com.au/forum/s...d.php?t=145365
I sold it for AUD $ 500 eight months ago, including three new Plossl eyepieces to get a beginner going in astronomy.
I paid US$ 700 for it (without eyepieces) five years ago, excluding shipment - so somewhere in the range of US$500 to US$700 would be it's approximate value.
My unit was also hardly used as it was part of a massive telescope collection (over 150 units) which I have been trimming actively for some time.
They are rare. In really good condition they are suitable for enthusiastic collectors, or for a beginner to astronomy.
Good luck.
Rgds,
Cris.
