I have the Lincoln 3200HD I bought new from e-bay almoust 2 years ago...(I hardware store was clean out some extra stuff) works great, I bought the gas cyl. for it and it works much better then using the flux core wire...I wouldn't even was my time, get the gas cyl right away....I forget what I paid, but I know it was cheaper then the one I saw at the Homedepot a month later....it didn't have a cart, like the one you said at homedepot did... but I know I paid in the real low 300.00 range..
