Spark Fun Electronics-Rotary Phone

If you follow the link to Spark Fun Electronics(lifted from uncrate), you'll see a sweet rotary phone that accepts a sim card, has 10hrs talk time and 4-5 day standby time. The reason why I love this so much is that when I was growing up we had a rotary phone until like 1990. Towards the end we kept it around because it was a great little curiosity. I was thinking of getting vonage service just so I could use one at home, but now I can just get one of these!
