all in all, as i said before, its gonna come down to personal preference on what you like the feal of... all the bikes that CptSydor lists as top runners, if properly maintained will last a long time, its gonna come down to preference... as someone else had offered earlier, if you or the original poster are up this way, shoot me a PM and i can show ya what the king quads can do...
one thing to keep in mind is honda and suzuki have bin making atvs for 30 years... in that time im sure they have learned a thing or 2 about building them... to me best choice new is the kingquad 500, followed by the foreman 500, again though, belt drive vs gear drive...
power wise buy what suits your budget... i never planned on buying a 700, i was actually on my way south to pick up a 450, when my local dealership who i know the owner at, called me and said he just had the 700 come in on trade, with only 800 kms on it, and i got it for less money then i was gonna pay for the 450, and actually enjoy the 700...
one other note to pass along with regards to the foremans... this comes right from the owner of a local dealership: stay away from the electronic shifts, they were haveing problems with them, that was back in 2010 mind you, so hopefully they got that resolved...
