I am surprised how little they cost.

I just did a search on Google and found a site, where you can get a pocket model for a couple hundred dollars.

Maybe people should be be encouraged to buy them, or the government could sell it to them at a reduced price, and if a lot of people had them, it would be harder for the terrorists to transport them in trucks or vans, or store them in a garage in a city, without someone noticing it.

Try eBay - they're about $20 last I noticed (it's been a while).
