Lincoln invertec 250

Has anyone had any experience with an invertec 250? I've had it in the garage for a few months and haven't hooked it up yet.. Just looking to hear about how she welds, the availability of accessories and reliability...

My other machine is a Miller maxstar 150s.. And I think I know the answers, I'd like to know opinions on running other processes on the machines and which is the better/versatile all around machine for small shop use..

Thanks!
