hmm ... interesting
Here's the rest of it:
http://www.d20srd.org/srd/magicItems/intelligentItems.htmAn Ego score of 19 gets you the auto try to dominate feature going.
PAO twice, the first time into something with high Int, the second to turn it back into the item.
Before that, pick or hope the Wis and Cha are the higher scores.
Telepathic ability - doesn't have to be just the table version, you could get a cheap limited Telepath Item added on.
Read languages ability - again an Item version via spell, would be cheaper.
Read magic ability - again an Item version via spell, would be cheaper.
Looks like those are the less expensive jack-ups, then you are back to whatever the Int Item stuff goes.
You need to be able to reliably beat the DC yourself, to be able to use it.

Nice find !!
