I have the prefinish floor thru the whole house....at the time the price of un-finished boards(~$65m2 cheapest) was more than the prefinished stuff($50m2)....so way cheaper to get it down, and then if you want you can sand it all and re-coat it at a later date.

We are waiting to ours shows enough wear to need the re-sanding...I did a lot of research first on how and who to lay the floor, it needs to be comopressed with special tools/clamps pinned into the concrete every 6 boards and then hidden nailed, and so on. Turned out there was only a couple of guys in wa that do it right so we waited a few months for him to be avaliable and it came out very good.
