I found the hotplate at Walgreens and was able to take it apart from the plastic base. This also allows the controls to be outside of the pot (the drainage hole is perfect for this!)
Just got back from Home Depot, where I bought the rest of my materials. Here is the full list:
2 X 16" plain terra cotta pots
3 X terra cotta feet
3 X bricks (to go under feet)
1 X broken brick (to support hotplate and keep center hole clear for air and wires)
1 X Replacement grill thermometer (fits nicely in the drainage hole for inverted pot cover)
1 X Replacement charcoal grate for Weber grill (the smaller one where you put coal)
1 X Hotplate
1 X Heavy pie tin (for wood chunks)
Going to do a test run this weekend. Pork shoulder or brisket.

1 X 10lb bag hickory chunks
