Thanks for all the info guys. Some great info and I understand. Now the debate of going Avin vs. Dynavin. I have read lots on each. Seems to be a fair amount of people have issues with the Avin, but others love them! Dynavin seems way to go, but the price point is significantly higher. Pondering....
