Most Arca-Swiss quick release plates cost between $30-$50.The new Joby UltraPlate quick release plate that's Arca-Swiss compatible is only $19.95, plus it has a few very handy features.
I have the UltraPlate mounted on my Canon 60D. When I'm on the go, I attach the new XXL UltraFit Sling. If I need to mount the 60D on the tripod, I don't have to remove the sling. I just slide the camera into the ballhead with the strap still on. Very convenient!
