Anybody try Pure Talk?

We have a 3gs, 4, & 4s all on Pure Talk. My wife and I are not heavy users so did not get a data plan - we pay $15/month total for two phones sharing 190 minutes/month that roll over (we currently have 564 available). My son had the Unlimited plan at $45/month which gave him data as well.

For light usage, it cannot be beat. However I believe StraightTalk is better for unlimited usage (more data @ same price)

Also - I had to deal with Pure Talk support once and they were fantastic - very helpful, patient and stateside.
