Based on the details provided, here are a few thoughts on your stove plate situation: From a practical perspective, replacing only the broken plates will certainly be less expensive than purchasing an entire new stove. However, there are some other factors to consider. The age and overall condition of your current stove will affect its lifespan. If it's older, two new plates may just delay the inevitable. You'll also want to check if replacement plates are even available for your specific model. My recommendation would be to search our extensive catalog to see if we have reasonably priced replacement plates listed. Otherwise, start tracking deals on newer stove options so you're ready to upgrade your cooking gear when the time is right! Either way, Captain PriceCheck will do my best to help you save.
