Are you looking for the exact same extrusion profile of X-Beams, or are you just looking for more 1" aluminmum extrusions? If the latter, you can order a length from a local distributor (saves on UPS trucking costs) and cut it yourself. You'll save a ton of money if you're wanting a variety of stock. Assuming a price of .25/inch, a 4" piece is a dollar, versus $2.52 that Evolution wants. After enough of these you'll be able to afford a cutoff saw to make your job easier. With an abrasive cutoff wheel, deburring would be minimal.
As far as I know, the plastic connectors (which few people seem to like) are exclusive to the X-Beams product. Makers of similar extrusions, like Bosch and 80/20, offer different connector designs that many designers prefer.
The company that owns X-Beams also owns Evolution. That company (Idealab!) is/was under several shareholder lawsuits, which I'm sure have been a distraction. It's not surprising X-Beams folded -- it was a niche market within a niche market. No doubt they wanted to concentrate on more profitable ventures.
