in and out of 4x4
#4
The Polaris line all have in and out 4X4 which allows for all 4 wheel to drive and no need for limited slip like full time 4X4s. It also alows you to play around and do donuts then switch to 4X4 when things get deep. My 1993 has been flawless and I am buying another Polaris...this time a 4X4.

From a sons perspective, the Polaris Magnum 500 can't be beat. He'd be happy for a long time. Just make sure you know when to shift into low range. The Honda 400 is sweet too. Did you consider the Yamaha Kodiak? The Kodiak is just a smaller version of the Grizzly practically. It's a 400cc 4x4, and is (from what I hear) a good quad. Keep these three in mind.

You said cheaper, so I will start from cheapest model for brand.
A/C - I believe all Cat's now have 2wd 4wd selectable, and they either are or can be easily modified (some by playing with adjustments, others may need a linkage arm changed - varies from machine to machine). Start with the 250 & go up. They also have a fairly good suspension system. Cats are good, solid machines, but not fast. For getting there, they are great, but not for getting there fast.
Polaris makes several models to fit the bill. Start with the 250 Xplorer on up. Being a 2 cycle, it will keep up with the 300s and most 350s. Reliable for a 2 cycle. Next up would be 325 Magnum. A good machine, but slow and heavy. For a few $ more, you can go to the 400 Xplorer. This is where things get interesting. It is a 2 cycle machine, lighter than your Grizz, and about equal in performance. With the Polaris 2 cycles, no mixing of gas & oil is needed. Gas goes in one tank, oil another. From there, the 400 Sportsman, close in performance to a non-HO 500, the 500 Magnum, and finally the 500 Sportsman HO.
Polaris in general offers a good smooth ride (the Sportsmans are the smoothest out there right now) and are easy to drive. I THINK i got them in order from cheapest on up. As a note, the Xplorer models are chain drive (as are the scramblers), the others are shaft. Somewhere in there are the Scramblers, arguably the best "fun trail" quad out there. Not the fastest, just a fun, easy to drive 4x4.
Yamaha also makes a couple machines with selectable 4wd, but I am unfamiliar with them as we don't have a dealer worth a darn around, so I don't look into them much.
