FX T12 and Regulator

I'm considering regulating my FX T12 FT. I'm considering the Audrius because it's pretty cheap, and seems to work well. I looked at Huma, but Trenier and AOA don't list one for the T12. Krale lists one, but by the time I pay shipping it is double the price of Audrius. I also considered a Lane, but prefer not to drill the hole.

To anyone who has ever installed a reg in one of the many variants of this gun, what kind of results did you achieve? 

To anyone using an Audrius, are you happy with it, had problems? Does it come with a plenum?

Any tips/pointers would be appreciated as this is virgin ground for me.
