Hi Jack,
Thanks for your kind words!
Yes, the FD lenses do give that "retro" look. They are slightly softer than the modern digital counterparts, especially with the aperture wide open (it's way too soft then) so you do lose a stop with them, but considering how much cheaper they are than modern primes, we think it's worth it.
You can pick up cheap FD lenses on ebay - just do a search for canon fit FD lenses.
We did a post on our blog about them it some time back...

All the best,
