220 is the way to go if you're investing in one.
But, I do like the portability of a 110. I'm probably going to get a Hobart Handler 140. Northern Tool has free shipping on them

If you want more local, I know that the Atwoods in Arkadelphia has a ton of Hobart welders and supplies. I was drooling on them the last time I went down to help Glen with his truck.
