Booboos heal and teach lessons ...

said by Jon5:Not sure how pricey but what about Ipe? Supposed to be tough as hell.
Ipe is hard, yes. But that's really a Janka rating measurement. Scratches and things, not matter how hard the wood, will still happen. And, it probably costs more to refinish the floor rather than simply putting down cheap laminate and then ripping it out later.
