Welp, everything is rusted and and in really bad shape so I am going to replace it. The model is a 0523-126Q-G588NDX. My question is what is difference between other 0523 models and this one? This one was doing well, but since I have to buy another one I figured it'd be smart to look around. The wife is already expecting it to be around $500, so I need to stay close to that.

Thanks
