As you price filters, you'll find a significant increase in cost from 58mm to 67mm. And stepping up to 67mm will probably preclude the use of a hood. So consider whether the additional cost is justified for the one 67mm filter size lens you have.

A "wanted" ad in the classifieds here might turn up something useful. Used filters sell pretty cheap. And sellers here (as well as some other sites) tend to be more reliable in descriptions than the norm on ebay.
