I would not go with a regular SIM because I would like to be able to create e.g. a remote burglar alarm without paying for (and getting a contract for) another "real" cell phone. That is, I'm not talking about using the SIM from my personal day-to-day cell phone to experiment with some fun little project, I'm talking about making a device that I'd like to leave on all the time. I want a SIM that gives me the best value when I use it to transmit at most a few KB of data per day, no voice, etc. Even if I added another line to my family plan for 10 bucks (plus, in my case, $6 or more per line for data), I think that's a contract extension, and if I decide I don't need it anymore after a few months, tough luck for me.
Ideally, I'd like to buy a 30-50 dollar prepaid mobile card, which is good for at least a couple of months (forever would be better), and be charged X cents per KB of data I transmit with it (where X, hopefully, would be ~3 or less). I haven't found that yet, because nobody's pay-as-you-go plan page ever ever effing ever talks about data rates (or if you can even do data at all).
