Aftermarket unit is about $350-$400 I think? Depends what you get... just had mine replaced a couple of weeks back because the fucking plastic end tank on the hot side developed a hairline crack, happens to all of them eventually.

Genuine Subaru item won't get you much change from a thousand bucks I think.
