I am surprised that noone yet has offered advice to your important problem. i am in the same predicament: i got differing opinions on what lasts longer, water stain or oil. most companies i talked to recommended the oil (polyeurethane) base, though, and that makes sense to me. water base, i hear, needs to be re-applied every ten years, while poly lasts up to 30 (?). the fumes supposedly are short lived but is there an issue with ecology? in other words, how unhealthy is polyeurethane?
