I forgot to add that like most things in life it just all depends on how you're going to use it. Not having pulsing is not the end of the world for 95% of what we do in our hobby. It certainly helps on thin material (it does help with heat control).... but lots of times I just weld without it.
Having the Diversion model will allow you to do aluminum. For me - that would be more important than having a machine with pulsing but no A/C = ala the little Maxstar. But if you don't plan to do any aluminum - and just want to do bodywork and sheetmetal etc - then the Maxstar will get er done.
The beauty of these machines - they're all worth something should you decide you don't use it at all - or you want to move up. So either way - it's a decent investment - unlike the wifes vacation that is just money down the tube.
