I have had a Glenwood Gold for over 8 years now and it is still running.  From what I can tell this is far longer than is typical, at least for South Texas.  Not only have I found the build quality to be excellent, but I have also found the post-sales support from Havenmade to be personal, helpful, and never rushed.
When it does come time for a replacement, Havenmade will be my first stop.
BTW, I seem to get a better deal on  my spa supplies here also.
