I posted about the Great Planes Magnetic Building Board System last week and ended up ordering one. I don't think you can go wrong. I'm gonna give it a try, if it doesn't work, I'll just sell it on to somebody welse who might want to build using the system. From what I understand though, it's a different mindset to building with pins.

Unfortunately, I only get it this weekend, so won't be able to tell you what it's like to build with until a couple of weeks time.

Good Luck
