@stubblebum - The pics you posted are cool, but it seems like a lot of bulk for a little portable grill. I usually just put my SJ on my performer table or on the grate of my 26er assuming they aren't in use. Otherwise it just goes on my concrete patio. I don't have any more room for a table option for mine, so I can't really speak about aftermarket or DIY ideas, but there is a good review of the weber table here if you have not seen it yet. I think its cool that the grill actually locks into place.
It looks similar, but not exactly, like the ones that these folks make:http://www.ardentgoods.com/
