On a side note if you buy the prepunched and predrilled panel kit from Ebrewsupply the build time for me with 0 electrical experience outside of changing a few house fixtures, was 16-20 hours. I worked on it at night for a couple hours when I had time. It was fun and a learning experience. I feel confident that if I needed to replace any part for repair I could. Which is nice. Because I choose the painted enclosure I saved $550 which is about $27.5/ hour I worked on it which is a hell of a lot more than a stay at home dad makes per hour : p
before i bought the spike system I would definitely consider pricing out everything separately and then making a decision. The panel really isn't hard to build and Ryan @ ebrewsupply has been great in my experience.
I also have come to the opinion after using spike v2, Blichmann, SsBrewtech, and Bayou Classic kettles that the boil kettle and hlt kettle need to be able to hold liquid and that is it. If doing it again I would find the least inexpensive yet still quality kettles for those two spots.
Kettles - Spike, SsBrewtech, Blichmann, Update International Etc.
Mash tun - This is the only kettle where I think the name brands actually matter unless you are pro at diy mash tuns which I never was.
Fittings - Bargain fittings, brew hardware (all the same Chinese stuff)
Pumps - wherever they are on sale or used
Panel - Ebrewsupply (where I think spikes are from)
Coil stainless brewing (where spike used to source theirs)
Just my two cents... piecing out is a bit daunting butI have no doubt you can save $750 - $1000 parting it out which is 4-5 ssbrewbuckets or possibly a couple of spikes new conicals.
