I've heard about Quark series for a long time,but it was very hard to get one of those in my country until last week I found a dealer here who offeres Quark AA-T with a price of about 46 dollars. 4Sevens' website said that they could provide 240-month warrenty,but that dealer claimed only two years. Is that a good deal though? BTW I found many of Quark series are "discontinued" on their website. What's that about?
