AMAZING Lego Compatible Roller Coaster kit from CDX Blocks.

I have wanted to build a real Lego roller coaster ever since I was young, and a couple of years ago came across these people on a kick-starter campaign. Unlike other cheap imitation blocks, this is well made, and I have bought half a dozen back from the US to make a mega-sized one like this:

Attached is a photo of the one we built here in Auckland; it works fantastically well, and my 8 year old loves it. You can also motorise it with a Power Functions motor from Lego.

I have a couple of spare that we don't need; both have a slightly damaged box - see the bottom right hand corner of the photo showing the back of the box.

These truly are amazing, and make a fabulous addition to the amusement park theme Lego seem to be developing (carousel, ferris wheel, fairground attraction etc...).

Happy to combine shipping if you want more than one, and can do a special deal of $500 for 2.

Questions welcome, no swaps though.
