The 711 Speakout is great. The basic phone is $60. It comes pre-activated with a phone# and some airtime. No need to call in or register (no name, credit card or ID required). The $25 airtime card is good for 1-year (most expire in 3-months). Per minute rate is 25 cents (if you buy the $75 airtime voucher, your rate drops to 20 cents/minute). The only monthly fee is a 99 cent 911 fee that is deducted from the pre-paid balance. It comes with Caller ID and voice mail. . It operates on the Rogers network, so I find coverage is good.
If someone refers you, you (and the person that referred you) gets a $10 airtime credit.
I just use it to make the discrete calls, then shut it off until next time.
There is a website that someone set up for info.

You can even get referral codes on the forums section of that website to get your extra $10 airtime credit

For someone using only a couple of minutes a day, I think it is the best deal going (plus no ID required, totally untraceable)
