i have a gso and they have changed alot since i got mine. optically i cant complain and i got more than i bargained for... some of the old pros will come here and say "how can you say its great, it mass produced rubbish", alas the are comparing to thousands of dollars worth of gear and for the price you will not find better. my 8" is now mounted on an equatorial mount (tripod). and years down the track i still think it rocks!
