In my opinion, all woodworking can be done with a circular saw, a drill, a chisel, and a straight edge. After that we get tools as a way to more efficiently do what those can and the money one is willing to spend on tools is based on the balance of how valuable you view your free time vs the time spent on a project.
Truth be told I am probably going to be purchasing the Lamello to take advantage of their Clamex system. I live in a 1950s house with small hallways and small doorways and I don't have the luxury of building 30" wide units in the garage and maneuvering them into the rooms. I am going to be building these in the same style as the IKEA Pax system but in either walnut veneer or white oak veneer plywood from Brazos Forest (only use them because I'm in East Dallas and don't want to drive another 25 minutes to get to FW Plywood). The clamex system allows for easy assembly and disassembly in the garage and transport through the house.
And then, if I can't think of any other projects I need it for, I sell it for only slightly less than I paid for it since the demand is high for it, and the little money I lose on it is far less valuable than the time and effort I would have spent trying to build these closets to the sizes I want in order for them to function they I want them to.
For reference, this is what the master closet is going to look like with the exception that all the double vertical panels you see are when I was designing this as five different units and those would be changing to single vertical panels.
