I am new here and it seems like a good place for advice. I am looking to buy a 350P with a push pull set-up for aluminum. I would like to find a good used one reasonably close to where I live. I found one about 1000 miles away that is about two years old. Is there any improvements from 2008 to a new model? The one I found looks to be in good shape but it is a long drive just to check it out. I may be better off buying new but that is a chunk of change. Thanks in advance!
