I think it's a heck of a strong possibility that it's a TA 3-pin crankset and thus you'll need that 23mm puller. Still, $10 from your LBS is cheaper than trying to track down a one to buy (though that's an annoyingly high charge). I'm surprised that your SuperCourse MKII doesn't have a Stronglight crankset, but then you'd need a Stronglight puller.
