I'm all about top notch CS. Most will pay extra just for that reason, myself included. Not trying to make that a majority factor in these questions. Its like a full service car wash, some will open your door for you and call you air/mam, drive the car for you, unscrew your antenna etc.., but when you get in and drive away, you notice they didnt even move the mats to vacuum....Others don't do any of that, yet the employee is on his hands and knees cleaning the spokes of your rims.... Bad analogy, I know...
However, I was meaning more towards the product itself side of things. Again, just questions from an under-informed consumer trying to make the best choice in available products..
