I would've made even simple weapons cost in the thousands so you think twice before buying that steel sword.
1) That's silly, for all sorts of reasons (think about it... if basic equipment - and steel stuff is pretty basic - is that expensive, no one would be able to equip their town guards)
2) Unless you make the "buy/sell" ratio incredibly unbalanced (like, shops only give you 0.1% of the value), crazily expensive equipment just means you'd have millions of gold once you sell all the loot you find in caves. And, again, having that twisted an economy is irrational. (ex: No one would ever sell used games to Gamestop, if they offered you 25 cents for a game while selling them for $1000. They'd just open their own shop, or sell them on eBay for a tenth of that. Followed closely by Gamestop going out of business.)
As for Daedric and Dragon stuff..... seems pretty rare to me, I found a whole four or five pieces between the three kinds (Daedric, Dragonscale, Dragonbone) in 90 hours of play. And finding them was pretty notable to me - certainly felt special.
