I'll see them again tomorrow and try to check.
Oh, and I remember there was speculation on whether or not the ETSC 2 can sit upright without tipping over on its own - the ETSC 2 150 can and is balanced by the sanding pad. The 125mm pad is too narrow and tips over.
Both will be sold for $56 more than the corded versions and include two batteries and a charger.
And the both use the same sanding pads and 5mm screws as the ETS EC versions - for you intrepid thinkers out there...
