Anyone used the new Z240 Snoot set from Inon?

Inon Snoot Set for Z-240/D-2000 [ino.4562121435841] - $274.90 : Reef Photo & Video!, The Underwater Photo Pros

I have not used a snoot before, but I like the idea a lot.

The Inon looks good but pricey. Debating whether to splurge, or experiment with a DIY. I also heard that reefnet is making a fiber optic snoot. Anyone know of a release date?
