As several of you have mentioned the 570 is built as a PRO saw, and here in the US is marketed as a PRO saw (though i tend to sell it to homeowners who have a lot of land). And as for the EPA thing, I find it funny that Europe seems to be behind the US as far as emissions on small 2/4 cycle engines yet seems to be ahead of us with automobiles in that respect. go figure...and with the 372, i think whether or not the US gets 1 last run of 372's (we havent been able to order one since early 05) depends on if they have enouh EPA credits from other units that exceed phase 2 compliance(372's don't even meet the 2005 standard). I've been told it's still a maybe regarding 372's in the US. Not all units have to be compliant, just the average of all units must meet the standard at this point (eventually all units will have to individually meet the standard i hear)
