Hey Ken, I bought some el Cheapos from Gordon Food Service for around $20. They are not fancy, just some wire racks to hold the Sterno, and full size disposable aluminum pans for water w/ Half pans for the food. I only use them every now and then for picnics, but the racks nest in each other and the pans fit well in the trash can.
They seem to hold up well, as I usually put out about 10 lbs of beans out in one of the full trays at a time. The $20 was for 3 sets w/ 6 sternos.
