I'm in the floors club, too.
Hardwood floors are a permanent and enduring value. The appeal holds across cultures.
If you are already in the project frame of mind, go for the hardwood floors. Adding or replacing appliances is a minimal inconvenience. With construction in a slump, you will find labor costs competitive, too, if you're not going to do the work yourself on the floors. I vote for wood floors.
Another thought: Something that changes in time - a style - is not nearly as nice. Tastes may change next year. And yes, appliance styles come and go. Because they are appliances, they have considerable use. On both counts, they are going to lose value.
The value question is a question I am asked all the time. I have friends who have lavished on upgrades. One friend has every possible gadget, spot lighting and, yes, stainless appliances, as well as plantation shutters throughout. Very attractive. But he did go over the top when he lined his garage with tile.
Another friend has replaced his hollow doors with solid doors (that he picked up for a bargain - actually a steal). And they all have replaced their carpeted stairs with hardwood. They love their homes and I enjoy seeing all the work that has been done when I visit.
As far as value is concerned, generally an entire kitchen renovation is the best improvement for recouping your investment. I'm usually advise that I would definitely do these things for my enjoyment and my family's enjoyment. If there is an advantage to be gained, it will be realized when you go to sell your home. Homes that show well move more quickly, especially in a buyer's market.
Enjoy your home.
A properly installed Hardwood floor will bring more value and beauty over the long run. The return on investment on the appliances will be hard to get on the short and long run.
