Glad you guys liked... let's see... firstly--I do not believe in a "style". I completely agree with Bruce Lee--the best style is NO (particular) style, the best way is no (particular) way.
That being said--when you break down saber spins (we've done a bit of this on NCSCS, and you can NATURALLY find more about saber spin terminology on Banditcar's Saber Spin Tutorials)... there are really only so many ways to spin a saber--so just practice mastering all of them... and then enjoy going "free form" sometime.
As to a gallery of sabers... I don't know, mostly "no time + no desire" to do so, and also because--it'd be silly. Most of the saber props that I have that AREN'T shown in singular videos (Flange III lightside, Flange III darkside, Flange IV, Charontas III--which is a saber staff, and about 3-6 other interesting sabers)... are just BASIC SABERS. They are meant for children's classes, events, performances... and generally get hugely beat-up.
In general, I care very little about the outer design (for MY purposes)... it's not what is outside, but what is INSIDE that counts.
As to the Obsidian-driven saber in the HD saber-spinning video, it is a compilation of parts, but primarily made of a 1.5" sink tube and a "false" emitter (which happens to look like an "Obi-Wan"-ish emitter).
