I know the new owner/maker, and he'll ship anywhere, but I don't know what his distribution plans are. It might be a small enough market that he'll stick with direct sales.
The new one will be more expensive than the old one, so if you only need to measure downforce, it might be a bit overpriced. The other stuff will be nice to have if you can afford the kit, though.
On the plus side, I would not be surprised if a lot of current/old MagnetMarshal owners decide to get the new one, and then post their old ones up for sale. The hard part will be catching those when they appear.
