Sub Floor Vents

We are considering going on yet another splurge. This time on sub-floor vents. Some (not all) older houses have a decorative design in the sub-floor vent. I have also seen the regular checker-board matrix of squarte holes on period homes too, so technically we could use them as they are cheap.

I have found two decorative sub-floor vents - the cheapest one is shown below. I am happy with this design, but the cost to do the whole house is high (we need about 50). Another idea is to just put these on the front of the house.
