Anyone know of a reasonably priced calling card that allows access internationally to call both back to the US as well as to other countries?

I tried IDT (GlobalCall) but have been very disappointed. They changed the access # in Germany and didn't update the info in their operator's database. They ceased all calling out of Singapore. The Indonesia access numbers (the three operators I spoke with gave me 3 different #'s) don't work.

MCI, Sprint, and ATT rates are SO high...$5 a minute on MCI from Italy 2 years ago cured me of that!

Any ideas? Solutions?
