The floating floor we've got is called Boral Silkwood and it retails for $70 to $150 a lineal metre depending on the style. (DH said he could supply, but I think the freight from Qld to Vic would add too much to the cost ) If you google it there's a brochure which includes installation instructions.

It does insulate a bit, so that is an advantage over polishing the pine.

I think polished floors are much better than carpet too! In fact we're buying a house with all polished floors. I'm gonna get some rugs so my DH doesn't complain about it being cold in winter.
