Hastings shotgun barrels - any good?

I have a Remington 870 TC trap gun with only a 28" barrel. I've noticed that most trap shooters now use 32" or 34" barrels. I've been looking for a longer barrel for my gun and run across a Hastings advertisement. http://www.shotgunsportsmagazine.com/hastings.html

Anybody here have one, or know anything about them? I'd like to buy one, but I'd like some opinions on them first.

Thanks
