Hello --

For the past few months, I have enjoyed using my grandfather's Canon TL QL. The camera had a 50mm/1.8 FL lens, and I quickly picked up the 135mm/2.5 and a Hanimar 28mm/2.8. I'm growing in experience with these lenses, but I'm considering getting another.

After a few eBay searches, I'm leaning toward a FD zoom, possibly the 28-85 or the 35-105 f/3.5.

Do you have any FD suggestions?
Is it worth it to get another lens (IQ, color, etc)?

I'm looking for prices less than ~$80 -- the two that I picked up were $40 and $10, respectively.
