Zerotract, the stock shift lever bends easily. MSR makes a quality
replacement, which I have on my bike now. It is much stronger than
stock. IMS also makes a great replacement lever.
I replaced my bent stock lever with an IMS. Ridden 50 hours on the IMS and no problems. It's pretty stiff so bending is not a problem. Outright snapping may be the other concern now.
I don't remember which one I got to replace the factory one. I looked at two brands though, I think moose and IMS. The only difference was one had a grey rubber tip and the other was black. Other than that they were identical. The two companies must just buy them from some supplier. It has lasted a couple years now and is good as new still.
