I have been looking at the PowerPro 256. I see these are currently out of stock, but more are expected in a month or so. Are there any plans to update this to digital controls like the 210 and 250 EXT machines? Also are the forum posts the only place where all the new machine info is available? I see the website seems to have a real lag in getting the new machines posted. I am mostly looking for a TIG machine, but having the ability to plasma cut on rare occasions would be nice.
