From the magic item web enhancement (pg. 3):
The ability for an intelligent magic item to have senses out to 120' and then be able to see with darkvision or blindsense on top of that is way too cheap. The total additional cost for an intelligent item with 120' darkvision is 1,500gp. For 120' Blindsense it's 3,000gp. Those prices are ridiculously low.
On the very same page an intelligent item that can cast a 3rd level spell once a day has a 6,000gp price add on, yet permanent 120' Blindsense is 3,000gp???
