Updating our home

We live in a mid 70s ranch style home. With that being said, most of the plumbing, cabinets etc are still original. I would really love to update our house so that it does feel like a newer home but without the high mortgage payment. One of the things that my husband and I have been talking about doing, is getting some discount faucets for both the kitchen and the bathrooms. Ours look so old and scummy right now. No matter how much I scrub them, they still look dull and have soap scum from years of someone not taking very good care of them. I can't wait until we replace them!
