MisterNice- You have done a great service by starting this thread. I'm surprised more people haven't posted here.

I've reviewed all 3 sites http://abletolls.com, http://10-10phonerates.com, http://easycall.net/ld#3
and have found a really good deal on 10-10phonerates.com state-to-state rates & call-time comparison charts, especially Clear Choice Comm 10-10-636, provided by VarTec, which provides 5c/minute 24/7, 15c/call minimum and no monthly fee in all but 15 states, clearly indicated on their link. I called the listed info# 1-800-760-1787 to verify the listed data. Basically, if you don't mind dialing the 1010636 code, it's like having the MCIWorldcom 5c Sat & Sun rate 24/7, on STATE to STATE calls.
