Servos

[Bill Glaze]

Eric & All:
What is the U.R.L. that Horizon is using for a complete servo listing?  
I've got one dialed in, but while it lists quite a few servos, it 
doesn't list anything in the 9000 series stuff at all.  Actually, it 
acts more like a hobby shop listing, than it does Horizon's official web 
site.  And, for some reason or other, Horizon's web site seems to have a 
security problem; must be the wrong site.  thanks.
