I've been very happy with my
Up-Strap which I've had on my E-500 for quite some time. It grips very well and keeps the strap from sliding around on your neck and/or shoulder.

However, I recently purchased the R-Strap RS-4 for my new E-3 from
BlackRapid.com and it's fantastic. The Up-Strap is better in regards to it holding everything in place, but the sliding motion of the R-Strap works perfectly if you like to carry your camera on your side. It simply screws into any standard monopod/tripod/collar receptacle.
