Some of the S&P's have exotic loot and treasure articles. Some are pretty cool (like the Dwarf treasure). Also, A&E, for all the heat it's taken, has some pretty cool stuff in it that, at least to me, has made some pretty good loot for PCs. Some of the items are treasures in and of them selves, so coming upon them in some Trolls loot makes the PCs eyes widen. Some examples are the Fairy Dust, Elven Silk and/or bow string, or some type of well made weapon or armor (Plated Cloak made of Elven Silk for example, or a lightened, spiked, hooked, steel Greatsword- Damage- 2d8+1, 6/14 AP/HP, ENC: 3, 13/12 Str/Dex, +5 to hit, +5 to enemy parry, double damage on Impale withdrawal- 4d8+2! A Hero's weapon! And simply because it's well made. I wouldn't give one of those to one of my PCs, but you can see the possibilities. That Greatsword is a Munchkin's dream.).
I have seen some stuff online that is more D&D random table style stuff, but I can't remember where right now. I will check when I'm back at my CPU (on phone now), and edit this post. I know there are a few good Glorantha sites out there with lots of resources. They are googleable, but it is more convenient and less time consuming to have the links.
Hope this helps.
