During this same period of time natural gas varied about | 230% with a nasty spike Sept 05 and Jan 06 where it traded for more | than twice current amount and I look for it to repeat pattern this | fall/winter too. These are all commodities prices not what they sell | for at end user but it show you how stable base price is or is not at | wholesale level. Of all of these LPG (propane) is the most stable | pricewise and it should con tinue to do so because supply exceeds | demand for it and will for some time too because the more fuel they | make, the more LPG byproduct they have. | -----------------

What you say may be correct globally but for whatever reason, locally the LPG prices have not been that stable.
Regardless, and I don't mean to be augmentative, but my contract for NG is both low and fixed for a long enough period that CNG is economically my best option for this project.
What I need to know is where can I source the hardware and how-to data to make the conversions.
