RE: Build with magnets (instead of pins)
2 Piece - Yeah... I always get them confused. Ernst makes the nice antenna exits and stuff. Well, I don't know why I had problems with the uprights, but I still think they are incredibly cheaply made. The thing is I was in Europe when I ordered it and I took leave specifically to build a kit. It took almost 4 months for my order to arrive because they sent it space available. I would have sent it back if I'd been here in the states when I got it, but after all that waiting, I didn't want to wait again.
I'm very happy with the system I have now though. I just need a larger board and I'll be set.
