I've seen some great FL lenses while hunting for FD's - I am thinking of actually buying some to use on my AE-1 - I saw a 50mm 1.2 FL lens for about the same money as a FD1.8!!! And if you hunt for Canon lenses, you will see that even the 1.4 are pricy. Look around, I don't know about zooms - but I did see some really cool primes.

PS Is eBay a four letter word?
