I have constant neck pain / issues. No problems problems with feet, legs, back, shoulders, etc. Just neck. Unfortunately it seems no matter how insignificant the lifting task, my neck is still involved.
I bought a little sub-compact Kubota BX2370 a couple years ago. It can "only" lift 500-1000lbs max (depending on the application), but that's still FAR more than me and I don't spend the next 2wks regretting loading / unloading / moving something.
