could someone please provide a short breakdown of the pros and cons of each and which you prefer? we have prefinished in our home right now and I've never loved the seams between each board. it's my understanding that site finishing is able to somewhat eliminate those seams...is this correct? We are building a new house and trying to determine which way to go. I think we are leaning towards site finished. Is there much of a difference in cost? It looks to me like unfinished solid hardwood is cheaper than a quality prefinished. But I understand that site finished will have more labor costs. Does it kind of equal out? And, finally, can we use wide planks with site finished? We'd like to use a 5" board but I've heard that's not necessarily wise with site finished. We're in PA. Really appreciate any help and advice that can be provided...thanks!
