In case yours falls through, don't fret too much -- I've got a good source in Japan where I can get them quite cheaply with the 2 player control scheme on occasion. I only mention this because I was thinking of making a post to gage interest on a similar, but smaller shipment to Houston (as I have a few friends interested in Houston, though I am in Japan).

Just an FYI -- if that bit of info helps your planing let me know.... Or if you have any good ideas
