short answer: ebay.

longer short answer: no such thing as cheap lenses.

Longer answer: my experience is to have purchased most of my optics from the same manufacturers that made my cutting head (haas-lti). the only place that I know for purchasing the optics outright is:

China has lens for cheap but it hard going back and forth with them, they don't always answer emails in a timely fashion.

China is in my backyard...I'm tooling around over here in Thailand so Shianghi or Hong kong, especially Hong Kong is right next door. See any good deals on lasers and associated gear over there? What about servos, drivers etc?
