Aside from the the display differences where the Pro 78's is easier to read (according to Veil) are there any more differences concerning these 2 detectors? I know they are running on the same platform and I wanted to know if the $20 difference in price is justifiable. CC has the XTR 690 for $130 via online purchase and the Pro 78 for $150, the XTR 690 is the cheapest I've seen from an authorized source when comparing it's price to the V940 and V955.
