Hey Keith - Custom build components like this will always have a higher price tag. This was built and tested exclusively for iStar. We have been using this mount about 3 months here in US and can tell you first hand it is "rock solid" even at 70mph. Plus you can "lock" the iStar onto the mount with a key which lessens the risk of theft. Something I have not seen on other mounts.

On the point cloud stuff, I believe you would need to look at the iStar Fusion.
