We need to replace an existing floor with oak hardwood to match existing floors elsewhere in the home. If we can find factory finish that matches the color we need, that would be preferable; however, if necessary, we would go with unfinished and then stain to match.

What manufacturers offer the best quality and durability for factory finished selections and/or unfinished?

I looked online for some reviews and there are complaints that some manufacturer products are less durable than others.

Are products carried by the big box stores good quality? What other options are there?

Any advice from your experience on which hardwoods would be the best investment would be greatly appreciated. I'd rather not ask prospective contractors as they may simply recommend what's cheapest if it's bundled with their quote.
