Mike, welcome aboard. We've got a lot in common, age experience,size and getting back into playing with dirt bikes at 40+ ! I currently own and ride often, an '04 KDX 220, it is a real blast stock and then easy to hop up as you want more out of it. I think you will be disappointed with the KLX's performance in comparison ( I have access to and sometimes ride an '04 KLX). If the dealer will allow a test ride of the '03 take it out and see what you think. The KLX is a good off road thumper but I 'm sure you will enjoy the KDX more if you plan on some moto type use and you will really want the 2 stroke rush :laugh: The KDX also has plenty of low end for general off-roading. Those prices sound OK but I would look for a GOOD used KDX for 2k-3k and buy some gear and upgrades (you will want taller bars for example and maybe a pipe) with the difference. There are plenty of low usage KDX's out there, thats how I found my '04. Have fun and keep us posted on your progress.BTW, as far as "going green", I was wide open to any brand when I was shopping around and rode all kinds of '99-04, 125s-650s, before I settled on the KDX.
