[3.5]Item CL- creating more powerful versions of items without paying more

[Tyndmyr]

RAW there is no justification for increasing the price of a wondrous item when one is crafted at a higher caster level using the item creation rules.

So, I can craft eternal wands at arbitrarily high caster levels? Seems doubtful.

There is also no justification for not increasing the price. And every known example of increasing caster level is accompanied by increasing the price.
