I've dealt with ORD a whole lot, & almost every part going on my project is a ORD part. I've always liked their customer service. Kert is awesome as well. He built an engine x-member for me and is now a full blown production. If DIY made more stuff for the Gen1 K5s, I'd use more of their products. However, for the price and availability of products for model, I'd go with DIY. I wonder how Kert will revolutionize the doubler...lol. just a matter of time......
