We are considering replacing a carpeted family room with hardwood.
Bruce has four lines that have appeal, but I can't seem to get any help
explaining the differences.

1) Is there a good reason to choose a 3/8 inch engineered wood vs. a
finished 3/4 in style where a 3/4 will fit without problems? I can
see where a 3/8 might be preferable over a vinyl floor where height may
be a factor, but we will be removing a full thickness carpet.

2) Any idea why the Bruce Springdale plank line is $1/ft2 more than
their Turlington plank line (both 3/8) when they appear to be similar on
store samples (same colors, widths, thickness, finish, etc)?

3) Any idea why their Dover View Plank is 50 cents/ft more than their
Valley View line (both 3/4) - again with what appears to be similar
properties, except the Dover may have a bit more edge bevel.

4) I've read that unfinished (carpeted) stairs can be refinished with
prefinished wood. Any idea on cost / experience.
