Here is a better link to Comfi's Spain-CELL cards,
The cheapest here is 9.3cents/minute, and that's from SPAIN-SPAIN-cell (exactly what a traveler would need traveling in Spain).

The only downside here, the 3minute rounding of calls (as opposed to 1 second), 99cents payphone surcharge, but all cards have that, so...

and by the way, timedial searches comfi's cards too, but places ??? next to its fields. They are usually at the bottom of the search.
Conclusion, Golden Lotus is by far the best deal, simply because it has the lowest SPAIN, to SPAIN-cell rates, at 9.3cents/minute. It also has the lowerst landline rates, Barcelona 2.4, and Madrid even less. It beats the Timedial cards, because their mobiles rates are between 10-38cents/minute, and none of them offer landline rates below 5cents/minute. They only benefit they offer are 1 second rounding.
That would be this card

It's one second rounding is appealing, but its 25cents/minute to mobiles, and 40cents/minute to Barcelona landlines, though Madrid is free.
So for a 3 minute call, option 1 would cost 9.3cents to call a mobile, and option 2, 25cents.
For a 30 second call, option 1 would cost 9.3 cents to call a mobile, and option 2 12.5cents/minute.
It appers that despite its 1 second rounding, the high per minute rates don't make it the better card.
I guess that shows that per minute rates to mobiles are the most important factor when choosing a traveler's phone card (as a means to replace cellphones, of course). What's the point of buying SIM CARDS in every continenet, or country when you can rely on phone cards, and use landlines to make calls (with the phone cards). Also, Webcalldirect (cheaper than Skype) is a good bet. It costs 15cents/minute to call Spanish mobiles on Webcalldirect (using internet connection), and landlines are FREE.
So, with Webcalldirect, and Golden Lotus I believe making calls (betwen 1-4/day) in Spain should cost no more than 10-20dollars for the whole month of November.
