Did you buy it? I have a Perfect 10 dish, and it's an excellent reflector, with great signal grabbing ability. The AJAK HH mount makes it all the better. That price is a bit high IMO, but not totally out of line, considering the Ajak is tested and working per the listing.
I believe it is a fair price considering that these ajak motorized dishes are very scarce and the dish is a perfect 10. You may have to reconditioned the half moon assembly if it hasn’t been used for quite awhile. Dissamble the whole mount clean and regrease. A bit of work but if you like the hobby and have the time it can be fun to do.
It looks like it needs a lot of work mesh ripped and dents all over it the bolts all need replacing after a full restoration job it will make a nice dish, just hope the motor works most of your money is in the motor imho.
