I personally would not get that one, as it is not aluminum capable. You may never build a frame from Al, but you might want to do other things with it. I would say that this machine would be very limiting. My rule of thumb is to try and get everything that I might EVER want in my equipment to do everything I might envision doing in the future. I can't always manage that, but I i try and come as close as I can. This machine is analogous to a 110 MIG. It may do 80% of what you want to do, but you're against the wall every time you need to do something bigger. I hate that! When you look back, you'll be glad you went for it. I balked at the extra money when I bought my Miller 250 MIG, but I've NEVER regretted it. My 180SD Syncrowave TIG is about as basic as they come, and I'd have liked something bigger, but it can do most anything I need to... so far.
Go big(er) or go home.
