We're seeing diy from the wrong angle, methinks. One prevalent motivation behind diy is creativity: design and/or construction, and enjoyment of operating what we made... While this value exists for the originator, it does not for the subsequent purchaser. Hence the remainder life resale value is low, barely covering the cost of the parts, as Twl notes.
On the bright side, another (important) factor is the possibility to gain access to the league of stratospherically priced commercial products; take, speakers, for example. The "legendary" ATC mid unit costs upward of $250 EACH. A 15" woofer from the same manufacturer will set you back another $600 EACH. Accuton (Thiele & partner) ceramic drivers -- as in Kharma & Avalon -- sell for upward of $200-300 each. A Raven2 ribbon tweet will set you back another $300 EA. Think of what the commercial speaker pair sporting (MANY) such units would cost!!!
Given time, LOTS of resilience and support, the diy may be able to approach (surpass?) the sound of the commercial offering for SEAMINGLY less. "Less" means that, lots of available resources are NOT counted in the cost equation: work-shed, bench, tools, electronic tools, the TIME spent fine-tuning the cross-over (say), friends' time who lend their ears, the beers & wine (that's for Tom) consumed in the creative process, etc...
