The worth of a Sharp microwave will depend on various factors, including the model, features, condition, and the seller's location or the market you're looking at.
Microwave prices can range from $50 for basic models to several hundred dollars for high-end models with advanced features and larger capacities. Sharp is a well-known brand with a range of microwave models at different price points, so the price will vary accordingly.
If you're interested in purchasing a Sharp microwave, I recommend checking online retailers, electronics stores, or appliance shops in your area to see the current prices and availability. Additionally, you can browse through e-commerce websites and read customer reviews to find the best deal that suits your needs and budget.
