Not counting Deadric Arrows, nor artefacts obtained in Quests, how long (roughly) do you think it was before you got your first Deadric Weapon or piece of apparel?
I never seemed to find anything, and with my first two characters I never got to the point of forging my own Deadric stuff either...the characters both ended up specialising in Light Armour, so there didn't seem any point. 300 hours on my first character, 100 hours on my second. Found nothing.
My third character I decided would work his way up the Heavy Armour tree and finally forge himself some Deadric kit. About 100 hours in, Level 88 Smithing, some Daedra Hearts and Ebony Ingots squirrelled away in a cupboard in Breezehome, he was out on a Quest and what did he find in an End Table in a dungeon? A Daedric Helmet.
Now he's forged himself the rest of the Armour Set, I'm not sure that I actually like it much!
