No problem. These numbers are approximate, but very close. Also, bear in mind that I didn't build this apart from some minor wrench turning. I could have probably done the plumbing myself, but I was eager to spend time brewing instead of working on the stand. Seems in line with the OP's intent.
I'm not including the cost of things like kettles, pump, CFC, and other stuff I already had. But that probably adds on another $1,000 or so. Also, not surprisingly, I went against my own advice learned from my last stand and didn't plan ahead for any possible thing I thought I might ever want to do, i.e. automation. So there was another trip to the welder for a center windscreen and burner mount as well as a return trip to the plumber to add the third burner (and ASCO valves for the TOP as it turned out).
Stand: 2" mild box steel, labor and materials $800
Gas Plumbing and labor: $240
Burners 2x ($75)
Casters: $40
Paint, nuts, bolts, water proof switch box, switch $25.
200 psi 3/4" hose, fittings, and disconnects $100.
Total: $1,280
Automation:
Return trip to the welder for windscreen and center burner mount: $120
Reworking the plumbing, adding 3rd burner and ASCO valves: $200
Another burner $40
CRT TV Mount: $30
Tower of Power Controllers (2x): $1,150
Total: $1,540
Grand Total: $2,820.
Construction time: 1 week from the time I dropped the drawing off with the welder; another two hours at a nearby plumber to have the gas pipe run. About an hour to paint, put on the casters, attach the pump, and wire it to the switch.
Automation changes time: 2 days at the welder for the new burner mount and windscreen (they just worked it in). 1 day at the plumber to rework the plumbing. Probably two hours hooking up the controllers, drilling holes, for the ignitors, mounting the controller stand, etc.
Obviously, if I had welding skills or was comfortable wiring up control panels, I could have done this for less. Not being a welder, I'm have been lucky to find a good local shop. This is my second brewery they have done (sold the first one to a good friend of mine). I don't think I could order a B3 system or Brew Magic and have it in hand such a short period of time either. As with anything, it would have been a bit cheaper if I had just had the center burner mounted from the get go. Hindsight is 20/20. Foresight will save you about $120.
