My top 3:
Just came across this one, but haven't read it yet:

May not be the right size barrel...
No, the cheap ones are semiconductor. According to the product line comparison from that BACtrack company, their entire consumer line of breathalyzers are semiconductor based. Ultimately, would you put a police grade sensor in a novelty phone accessory? That company's bluetooth based product is fuel cell based, so you're right the BOM might be a bit more. A product could be built on semiconductor sensors for that price and likely do well in that market. Maybe that is how the breathometer will position itself, as $150 for this kind of toy seems stiff.
It concerns me that they haven't developed a mechanical system yet. If they want to ship their alpha release with what looks like currently a Zen Toolworks machine (http://www.amazon.com/Zen-ToolworksTM-Carving-Machine-7x7/dp/B002ARTLUG/ref=sr_1_1?ie=UTF8&qid=1405603336&sr=8-1&keywords=cnc+machine) that's fine, but I would be very weary if these guys are saying that they're going to use kickstarter funds to develop and ship their own cartesian robot in addition to all of the custom functionalities that they're building.
No problem:
A router table is just a hand-held router that has been mounted to the underside of a table with the bit sticking up above the table. You can get ones with all sorts of adjustments or you can make one out of plywood.
Here's a video showing someone using one:

I expect YouTube to offer you similar videos of people building their own tables. They're a simple device once you own the router - you just want your surfaces to be sturdy, flat, and square to each other.
For your situation (a circle), I'd put a small board perpendicular to the backstop at a distance of 1 radius from the center of the blade. That way you can put your plastic housing up against 2 guides (the backstop, and this board) and spin it in place. Buy a router bit with the taper you want (example: https://www.amazon.com/dp/B00KZM1BTC/ref=psdc_3116541_t3_B001CGYOTY I'm not endorsing those, I just did an image search and selected one that showed a variety of angles)
