Yesterday I hit the jackpot, so to speak.
I saw a weird short ad on Craigslist saying that a guy has a bunch of inkjet papers for sale and he listed a couple of brand names.
Sounds legit to me, so I contacted him, agreed on a price and we met later. Little that I expected that I'd be going home with this:

* That's over 300 sheets of large format inkjet with names like Hahnemuhle Lumijet, Harman, Ilford Gallerie, Epson and HP, none of them are less than 200 gsm and most of them are Matte (my preferred compared to Glossy by far). In English: Expensive stuff.
But wait, out of his trunk he also produced this:

* About 700 sheets in total of the same quality stuff in smaller sizes.
I blinked, picked up my jaw, pull out my wallet and handed him four twenty dollar bills (more than what we agreed before), told him many thanks, and we chat a bit about printing (he's also a victim of Epson printer's not so clever design of irreplaceable heads).
So I spent some time last night printing one of my pictures on a 310 gsm 8x10 Museum Parchment while learning Canon's way to front-feed heavy papers.
It's sublime.
