I think what you saw, Larry, on the LexJet site was probably Hahnemuhle gallery wraps, which are a totally different animal. They have a unique design, and the corners look quite slick, with the canvas folded inside the corners of the frame's mitre, but they are a highly engineered product, not unlike something sold at Ikea. There isn't a sliver more wood than they need, and the fact that double-sided tape is used in the assembly means that these are depending on an adhesive product for a portion of their longevity. It's quite likely that they will last a very long time, as the design is undeniably clever, but the high cost and untested technology (over time) makes me reluctant to try them over less expensive but more safe options. All that said, for someone who has not stretched canvases before, these seem like a great way to get their feet wet with canvas stretching.
