Great Lakes Windows, Whats your story??

I am looking to get new windows installed at my home (Not Replacements) and three different businesses in my area that sell windows all tell me to use Great Lakes Windows. These businesses are on the smaller scale and not places like Home Depot, etc. I have seached this group and the last posted messages are from 2002 and I would like to get opinions either good or bad on these windows. Whatever insight you could provide would be appreciated.
Thanks Mark
