I prepaid an order for a 250-EXT back in February and was told the shipping date would be at the end of March. It's now the end of April and still haven't heard a word on when these welders might be shipped. I tried e-mailing these guys for an update but they just don't respond back. I might just have to lease another model Tig welder to get some jobs done if it's going to be another month or two or even longer?
