RE: Honda Foreman 4x4 / Rancher 4x4
Either will do fine but if it were me i would go with the foreman.
I have a 2000 foreman s and the thing has been awesome . i pull alot with it but i also just ride for fun. the newer version is probably a much better rider due the ability to go to 2wd. steering is probably much easier. not that mine is bad but would be nice to have a steering system that was easier on the arms.
As far as cost difference ....for me i wouldnt really worry but depending on how much you use the machine it would be a factor. but hey you may get the rancher and really start using it for lots and find out it might not have enough guts. and you may wish you had went with the bigger machine. i will bet when you get one and find out what you can do with them you'll be happy if you get the foreman over the rancher.
anyway good luck with your shopping.
