Are they still around as new, or do mean the old ones? I knew someone who had one and there were aspects I didn't like, iirc they only have a one-arm spider, which doesn't allow you to make adjustments easily. Optics were ok but nothing special.
The new series Starhoppers had an ota sourced from GSO, so it was identical to those gso's from Bintel, Andrews et al but with a different base and at a much higher price.
With the Synta takeover of Celestron, I dont know if this is still the case.
