Greg, it really depends on how you feel about the saw. It is a lot like a vehicle. If it is still running but you have reached the point where you are tired of spending money on it then it is time to replace it. Some selling points with regard to replacing the saw are that newer saws will be safer to operate and have better dust collection.
Another issue is the type of woodworking that you want to pursue. I replaced my contractor saw with a cabinet model about a year ago and couldn’t be more satisfied. It was a vast improvement, not only in the safety department, but also in the saw’s performance and reliablility as well.
I agree with Topamax’s comment that you can’t take it with you.
