Also, I don't know if you already have the Natural Gate or if it's on your wishlist. I haven't been able to personally justify the substantial cost or wait for this LPG yet. I know it doesn't have the same cool factor, but I just got the Takaab 2LPG and it sounds incredible. It's only 2hp and costs about $40. If you are in the market for an outstanding vactrol based LPG, the 2LPG is hard to beat.

As a very pleased Natural Gate owner, who has also used several other LPGs, my suggestion is to get on the waiting list for a Natural Gate if you want one, and pick up the Takaab to keep you busy while you wait. The NG is a very special module.
