Does it really make sense to use a rainbow pretender for site searching?

Depending on the magic site frequency and current actions/distance of your neighbors a rainbow pretender can be quite useful. Searching with a rainbow pretender almost provides the same value as casting Ashaic(sp?) Record which costs 25 astral for one spell. Sometime during midgame it's better to return the rainbow mage to a lab where all future time is spent casting spells, forging items and summoning creatures.
