here is my small control panel - it was cheaply done.
2 amazon SSRs = $26
1 amazon cash box for a box = $14
1 pid from auber = $45
4 lights from auber = $16
1 RTD probe from auber = $16
2 elements from a-boy plumbing $25
2 nuts from bargain fittings = $10? i think?
a bunch of misc switches from ebay = $10
extension cords (only needed if you're not close to the outlets) $70 (i brew on the back deck and plug into the kitchen outlets)
$162 without the extension cords
$232 with the extension cords
i had everything else from brewing before.
You could always go with some more bells and whistles for more money, or go without lights and go with less, etc.
this is about the best closest shot i have of the controller at work.
