Don,
I have Isspro and ditto all the good things already mentioned. I got a pillar mount from Geno's Garage. One thing I didn't see mentioned, is that if you get the pillar mount, AND wear bifocals... ... you have to tilt your head back a notch to read them #@$%!
And as Dave said, the angle is already kind of off kilter. But being as cheap as I am, I stayed with them. However, I do like the sounds of Jay Leonard's idea.
