All advice appreciated. The Archetype seems excellent (got 5, combining with 2). I echo Riffler, Royal PITA to assemble, actually even with a level. Aside from leveling, not hard at all...oh, but my demand for precision (which of course is an illusion, anyway). Seem like really strong, solid shelves. One more gripe - they're not clear about what you need. It wasn't until I started putting them together (having spent nearly $400) that I realized I was still missing "couplers" (another $25, and now waiting to finish until I get them).
