My Dux pens arrived yesterday.... I was very pleasantly surprised at how well they write... definately a fine nib, but puts out a reasonably wet line...
One definately writes drier than the other, but not desert dry.. just drier..
If you have not gotten one yet and have the opportunity GO FOR IT... well worth the couple of dollars they cost..
The ones I got were the Parker 51 clones... they are definately thinner than a 51, but the aerometric filler is really good and responsive.. and the sac seemed to fill almost completely to the top... should be a good time between fills...
