Two weeks ago I got a Televue Ash Gibralter mount with the SkyTour. However I managed to get ahold of a used SC so I dont need to have two DSC's at this point. I only tested the SkyTour once and it works as advertised. Its in new condition and will work with just about any set of encoders. Of course it will work with the Televue mounts with encoders (or you can get encoders to install from Televue on those mounts).
$285 which includes shipping (CONUS).
(new this is $300 without shipping)
