Hello vantage500man, haven't run this one yet, however one of the things that I believe it will show over any of the others is the lack of "puffing". I am referring to having a big blast of shielding gas when you initially pull the trigger and go to start welding, since the flow-meter is housed directly inside of the feeder you won't have the build-up of pressure that sometimes occurs when you have long runs of gas line and it is the type that expands slightly under pressure. I believe they also made some real progress in serviceability concerning having to gain access to any of the internals, the old LN's were a bearcat if you needed to gain access to anything inside of them. I also believe they made the front ends to accept standard mig guns instead of having to use the cumbersome adapters that the older ones required due to being set-up for the self-shielded wire guns initially, this could be real nice for you if you plan on running a lot of dual shielded or gas shielded wires. Not a lot but some things to consider. Best regards, aevald
