What do you want from the wood? There are many kinds, each gives its own
characteristics to consider:
I want to stain to a particular shade: oak, ash, birch (possibly maple)
I like grain: oak, ash
I like no grain (flat surface): maple, birch
I'm putting Jatoba ("Brazilian Cherry") in my high traffic LR/DR area. Its
very hard, way beyond oak, and reasonably priced. Its a darker reddish
color right out of the box, but its gorgeous.
There's a million to choose from, go to a store, see what you like, ask
questions there, look at prices, and just pick one, you'll be fine.
