Hi
Yes the software is free for life
GHL have been around for 15 years and the first ever model was designed and brought to the market in 2002 since then it has been developed continually into what it is today and continues to be developed further this year to a much higher level which all users will benefit from.
Progressive Reef are the largest supplier on the west coast yes, but not the only supplier. You can be assured of them having what you want in stock.
Hope that helps
