From HGTV's Front Door:
#10: The kitchen is one room where upgrades almost always bring a large return on investment. However, you don't have to gut your kitchen and tackle a major remodel to add value. One way to improve your kitchen is to simply replace your old appliances. Stainless steel is the current standard, but you don't have to buy the $9,000 commercial-quality Viking range or the most expensive Sub-Zero refrigerator. Any updated appliances will look better, run better, and give your kitchen more appeal.
