Prices are including shipping. As I mentioned, I bought some alternate parts (noted with *) in some cases, so this is not a complete "Kal Clone"

So, that all totals to $631.38 - again, including taxes and shipping. Tack on another $20 for package receiving at a facility in Point Roberts WA - most of the US sellers sent stuff there, most of the Chinese sellers mailed directly to me.
So, as far as I can tell, the parts I used were identical to Kal's links on Ebay and Amazon (which I used whenever I could) with the exceptions noted above. The heat sinks on the SSRs appear the same as the "Standard" 40 amp heat sinks described on Kal's site.
I haven't priced out the wires, terminals, or nuts and bolts, so I'm unsure on that, but I'm willing to bet it won't be more than $60-75. I was going to buy the terminals with the Amazon order but had trouble finding the right sizes and quantities (ie, I didn't need 500 pcs!)
I also skipped the handles - didn't think they were necessary.
Some other deals I found:
GFCI cord - $43 shipped from Hosfelt Electric - this took a lot of searching.
Camco elements $41.70 from Amazon (for two)
Auto-range multi-meter - $28.54 - Ebay seller smtzone, it's way nicer than I expected for the price.
Probably my favourite deal is the cords and plugs for the elements - 2xL6-30 plugs and 9 feet (on each plug) of the exact cord that Kal specifies were only $34 shipped from Ebay seller bb-breakers.
So, while it's not an exact clone, I feel the "important" parts are all the same. And if I have to replace a cheap amazon SSR down the road, well, I guess I'll learn my lesson then.
