Oh hey, another collector! I've been trying to do the same thing with green weapons, along with trying to collect every quest item / oddity in game. I have over 5 storage characters just filled with the stuff (two for the greens, and yes, I have a lot of free time, and I've been collecting for a few years). It's been difficult getting some of the more rare-but-unwanted greens, like several Sorrow's Furnace ones, since people are migrating quickly out of the game, so less people are selling. And farming with the low droprates can be frustrating, especially with bosses that are far from towns (requiring a long trek between farms).
On a side note, if you received any unneeded doubles from the generous donations you received, I'd be glad to take them off your hands. They'd go to a loving home.
