OHhhh, then my idea might not work. I was going to suggest that king look in TESCS for Oblivion at the different NPC merchants and see what is in their iventories. I looked at a few. I think what Hunter said about their goods leveling with you may be why I found alot of them only having the clothes they wear in their inventory. Maybe looking at Leveled Items in Obliv TESCS might help? If there is such a category.
* Ibis laments - Oblivion is so different than Morrowind in many ways. I read a theory by a guy in PC Gamer that Oblivion got dummed down for the Console playing. Bummer!*
