What's the highest CD for each grade of weapons? (realistic and non-extended)

Then help them out ^-^

Maybe I am just looking in the wrong areas but AH still sells crap all in the weapons department. Armors are great there is plenty both low budget and high end, but for weapons it seems almost no one is willing to sell anything above 30%. Someones hoarding all the good stuff and leaving the crap 26% behind >.>
