Great looking stand Oldtimer.
My thoughts on these stands are if you have the tools (welder, metal cutting tools, good drills, and the know how) then build your own by all means. If you are interested in learning how to build stuff and have the time then you may as well go about building one since like anything it can be educational. However if you dont have the tools, time, or drive to learn this particular craft (god knows in my case I have enough hobbies as it is) then it just pays to buy one premade.
Its kind of like buying leather working stamps or making your own. If you are skilled enough or wanna learn the craft you can make some excellent quality stamps, however the time and energy and money involved need to be weighed in comparison to just buying the better quality stamps to begin with,
