dust question

Wondering how much dust is acceptable inside a used lens? Went to pick up a used FA 50/1.7 today, shined a light into one end and viewed from the other end at least a couple dozen dust particles. I was alarmed and passed on it. I've never inspected much less purchased a used lens so I have no idea what is acceptable or how/if it will affect pics. Please share your thoughts/comments.

This currently active thread may be useful.

If you're not sure, though, always take your camera with you and take a few sample images with the lens.
