Miller and Hobart seem to share some common ties. As to whether or not they are all the same I don't know for sure.
$958 sounds a bit high for the Miller 180. When I was at the local supplier last week for some wire they had a tag on the basic 180 for $833. That of course did not include the cart or the argon bottle. Even if they are including the cart that is only another $50. If it includes the cart and the argon then the price is right. You might want to check a few other places no matter what one you have settled on.
At the same place the base Lincoln 180 was $795.
