I have the opportunity to purchase part of a collection. The part I'm interested in are the FIVE 1.0s. How hard is it going to be to track down original lenses as all of the pieces I'm considering purchasing are "Frame Only". I'll need the following lenses:

Black Iridium x 4 pair
Emerald Iridium x 3 pair
Gold Iridium x 3 pair
Grey Polarized x 1 pair

Before I agree to a price, I want an idea of what kind of headache I'm looking at getting myself into. I'm being told all 11 frames are in near mint condition.

Lenses.. not going to be easy. Even recently retired models quickly become hard to course out part, so 20 year old ones are going to be worse. Can always go the custom cut route, but those frames were before the 1999 O Matter change, so they tend to be brittle.
