I'm saving to buy one of the kitchens from Angels and Elves.
I had a wooden one and sold it when I closed. It turned out to be a temporary closure and I am kicking myself.
It was played with all the time. Loved it. The kids loved it. And it looked beautiful in the play room.
I have a plastic one now and the kids just try to climb in and out of the oven. (and it's ugly)
So yeah, I'd say go for it. If you decide you don't want it later on, the resale value is maintained in a wooden kitchen. (and they are heirloom items so will last long enough for grandkids - yes, it is probably a ways off but they do have a long life expectancy
)
