motivations shields are generally the cheapest, but depends from the skin...anyway except few skins, most req 9 shields aren't more worth than 15-20k. it's not much
And inscribable staves are also not so expensive, as well 10-15k for common skins..
Non inscribable is another matter and really depends from the skin and mods. Generally a 20/20 goes over 100k easily up to hundred ectos for particular skins.
20/10 also depends from the skin...but they are cheaper
And last but not least: non inscribable for ritualist attribute are a harder to find and i believe much more expensive than other attributes..
