so I have a BBC Big Buddy that I'm going to be upgrading to something a little bigger. I've changed over the heat controls to a digital PID instead of the rheostat type of deal that comes with the dryer, also have replaced/upgraded the "plug" that goes from the heat controls to the heat chamber, and put a cooling fan on the heat relay heatsink.
dryer has 24" belt 8' long, 4' heat chamber, and 6100w.
$2,500 let me know if your interested. I'm located in Northern California
