Just in case you still cared, I found the webpage for the owner of the Toyrific brand:

Looking at the large photos of the new Space sets, the components and manufacturing quality look like they're from the same factory as current Best-Lock, but as the Castle and Pirate sets use rendered box images, I can't tell if they're the same or not. I've found the Green Dragon set for £9 including postage, and like you I'm very tempted to pick it up for the minifig accessories (it also looks like it has some unusual coloured bricks).
