Value of Power Steering option

Per Kelly Blue Book, the current retail US price of an 09 420 AT with and without PS is 5345 with vs. 4915 without.

I have PS on an 08 foreman and I love it. I won't own another quad without it, and for the few hundred bucks on these used machines I'd definitely go with the PS if all other things are equal... and if you can afford it.

I'd try not to get in a hurry and just hang tight and try to find what you want. As soon as you settle for something you don't really want, something better will pop up for sale.
