Does anyone have experience with Goodmark or AMD e-body firewalls? I got a quote and I can get a Goodmark firewall for 1/2 the cost of an AMD. Has anyone used a Goodmark with few issues? I tried the usual searches and there is hardly any information available on the blogs or world wide web. Is no news, good news on this one? Looking at photos of both the AMD and Goodmark, they appear to be the same, and they both have a hook on the firewall where there should be a rubberized coated fold over type clip.
