I have an equivilent machine in the Fabricator 181i. I am very pleased with its operation. Although mine does not have the dual voltage capability. And as far as another cart, or swapping machines. I use a parts cart that I had built years ago and modified it to hold several bottles of sheilding gas and all 3 of my welders, along with all the leads and periferals. I still have about half of the storage space on the cart for parts and what other tools as well. I am not sure on the MTS machines here if they are dual voltage, but if so that would be great.
