You forgot the cost of the vehicle used (I drive a <a href=https://en.wikipedia.org/wiki/Rolls-Royce_Silver_Ghost&gt;Silver Ghost</a>–doesn’t everyone?–so that’s $200 million), the clothes to wear when on the purchase mission (I’m partial to the <a href=http://www.saksfifthavenue.com/main/ProductDetail.jsp?FOLDER<>folder_id=2534374306424607&PRODUCT<>prd_id=845524446661540&R=822289760976&P_name=ISAIA&N=306424607+399545629&bmUID=kffeWW6&gt;Windowpane Plaid</a> for such non-essential missions such as this, so that’s another $3K), another thousand for the cashmere overalls (with Hermes scarf cause it’s winter, you know), and also the education I had to pay for (spitballing here, let’s call it $300K, shall we?). I won’t bother with the cost of the roads, traffic systems, distribution systems (for the parts, yeah?), and so on, but golly gee that nifty thermostat is getting pricey, huh?

The stuff you mention is irrelevant and unnecessary to make the device. The laser cutter and CNC mill are not.

I have access to them at a local maker space, but that costs $100/mo and in any case the laser cutter is still down after someone mashed it.

Without those tools, the project is a lot more involved and costly.
