10-4 good buddy! The first post sounded like you were comparing apples to oranges, but I smell what you're stepping in now.Googled it. Seems very expensive for what you get. More Beer has this for $29.99. Standard 3/16" beverage line is $.79 per foot. Since your beer and lines should be sanitary, and cleaned regularly anyways, I don't see the need for anti-microbial lines.
You could basically get 12' of regular line for 1/3 the price of the kit.
You're quoting vinyl lines against barrier lines. Different animal. Vinyl will be sanitary but will leech plastic taste into the beer sitting in the lines over time. Barrier lines have no flavor degradation or crossover.
I realise standard vinyl beverage line and barrier beverage line are two different animals, but after 5 years of running vinyl, I'm yet to see off flavors. Some things, like Perlicks, are worth the upgrade, but to me SuperFlex beverage line does just fine, and I think there are better places to spend your money. Just my 2c
