My gawd what a thread....but it had all I needed.
Took me a while to read it all but finally got through it and built one. Works great for such a simple system. Had a ECB and Walmart $99 sidebox both of which are junk. The sidebox takes so much tending and the ECB peters out after 5 hours. This thing seems like it will run for days on a basket of lump charcoal. I have about $40 invested and its worth every penny. Its great to be able to put meat on before bed and wake up in the morning to a delicious hunk of BBQ.
Thanks to all who contributed to this thread.
Oh heres a pic because of course no pictures means it didn't happen.
