Sounds like you've done some shopping and research. With this in mind, which way are you leaning? And what do you like/dislike about what you've seen? Is this new construction? What do you have for a subfloor now, and what's under that? And have you checked into Engineered floors (from, say, Harris-Tarkett)? Do I understand that you're doing the work yourself?
Instead of me taking a lot of time to address a broader 'subject', I'll help you if you take some more time to share your thoughts with me on what you've learned so far, and which way you're inclined to go, and why. (Also, answering the above ?'s would help me.) I could babble too long if we were to go a different route. Patiently, I await.
