How accurate/reliable are the portable breath alcohol analyzers (breathalyzers) available to consumers? In particular, does anyone know anything about the CA-2000 manufactured by HAN International.

I’ve seen some on the Internet for under $100. If they are fairly trustworthy, then that’s a bargain.

Since you’ve already asked about this [elsewhere](http://boards.straightdope.com/sdmb/showthread.php?s=&threadid=192994) I’ll close this one.
