Are Fountain pen desk sets hip?

I tend to scour antique shops for unwanted fountain pens, and frequently run across fountain pen desk sets. When I was a kid, I received one from my family for a graduation present, and although I have always kept it on a desk or a table around the house, I never thought about it much.
 
Now, I think that they are quite handsome. I feel bad when I see lonely ones just sitting on antique shop shelves. Why do so many nice antique desk sets end up being ditched in shops, yard sales, estate auctions, etc.?
 
You can also find many brand new desk sets – fine ones still being made by Cross, Parker, Mont Blanc, etc. There are also quite a few handmade ones from custom fabricators and artists. I’ve seen some beautiful acrylic and wooden desk sets for sale online.
 
Do you collect fountain pen desk sets? If so, which ones are you favorite?
