The GX345 is a pretty stout machine and should last 30+ years, However, if you wish to replace it you will need to get a 520 series minimum, a 720 is a bit stouter than your 345. The 520 will cost around 7k with a deck and blower, 720 around 11k. Keep in mind the 300 series are much lighter duty today than your 345 is. The weak point on the new ones are the transmission and limited attachments.
