Interesting! Another very useful bit of screen scraping, just like your Betamax comparison table. Well done!! In time, when you add in other roaming SIM's this will become even more useful.
I just have 2 general comments. Is there any reason why the SMS rates for travelsim.com keep coming up as free? Are they really free? Also, it might be useful to add in the Data rate per kilobyte in the origin country, just like you show the have incoming call cost.
It would of course also be great if you can throw in some national SIM's though this is obviously a HUGE task to do!
