Looks like a nice stand. 11 gauge is still 1/8" thick and that's some beefy steel. $400 is a great price for a SS stand. I would look at the quality of the welds, especially in tight spots, and give it the sit test in the middle. If it supports your weight without any flex, you should be good to go. You may want to ask how much for a center support, but that would be it.
