Chris,
the $300 ones from Andrews will do for Visual observing. The scope you mention is quite long and a smaller mount will wobble more with long scopes.
I currently use an EQ1 for my ED80 and that is pushing every boundary!! I cannot get good astrophotography results with this set up, that's why I need to upgrade.
If you only want the mount for visual use, not astrophotography, then it should be reasonable.
I notice that Andrews has an EQ5 without motor drive for only $399.
Or same with Steel legs for $499.
That would be plenty heavy enough to take your scope. R.A. Drives for the same mount are $200.
Or R.A. & Dec drive for $279
That makes for a very good mount at low cost.
Through my investigations lately, it appears that there is no GoTo for these mounts unless you customise some other GoTo to fit and work.
The CG-5GT is $1249. Lots of dollars, but for Astrophotography it will be good.
If you aren't too worried about shakes and wobbles then he has an EQ3 with aluminium legs for $299. You can fit the motors to this one too. But probably not wise to go below that size due to the length of your scope.
