What are the best Value Canon lenses?

[Mason11]

I've had a few threads on your favourite lenses and canon's best lenses, - but what about the best value lenses?

Obviously top of the pile is the 50mm f1.8 - a staple of anyone getting into primes. I personally love the 85mm f1.8 - just got it and it's a beautiful portrait lens I got it dirt cheap used.

What are canon's other best value lenses?

EF 24-105mm f/3.5-5.6 IS STM. You can buy them used for about $300-$350. Up side; images as good as the L lenses, fast focus, quiet, light weight. Down side: 5.6 at the tele end, no weather sealing, no full time manual focus override as with USM lenses.
