Just got off the phone with V1 and have prices for the upgrade path. I have had my unit for the last 3 years adn it seems to be working just fine. I was debating a simple retune vs a complete upgrade. I have heard nothing but good things about the new 3.872 software. I was just wondering if anyone in here would shed some light on weather or not the upgrade to 872 was worth $100. the nice people at Valentine 1 seem to think it is not. Thanks for the input.
