This is not about value, they are for my personal use, what it's about is what do I call them.
And I disagree with your assessment of the shells. That cheap luan Mahogany after 30 -50 years undergoes a dramatic transformation, as the oils in the wood dry out they become harder and more resonant. The sound of these drums is fantastic once you put decent heads on them, especially if you like a dark warm sound. In any case, even top quality brand new Keller Maple shells are a relatively small portion of the expense involved in building a drum set. You can get a great set of Keller Maple shells for $250. It's nothing, yet they tend to be the basis for many, nay, most high end custom made drum sets.
Even top of the line DWs are based on standard Keller maple shells, and right now C & C is basing a line of high end sets on get this, luan shells, two kinds. Luan-maple-luan, and pure Luan.
Let me put it another way, you are certainly right in that I'll be spending a lot more on these than "cheap" asian shells would warrant. I might as well spend another $200 and get Keller shells instead. Problem is, I'd have shells that don't sound the way I want them to, and would have spent an extra couple hundred dollars for the privilidge.
It is the quality of the sound and overall set that determines it's value, not labor, not materials. That's why people pay $6000 for a high end set of DWs or custom made Tribes or C & Cs, even though they could get a set of Pearls based on the same shells for a fourth of the price.
Additionally,
Call it Leroy. You do realize that the only real value on the drum set is the expense in materials, time, and effort that you will spend. No mattter how great the finished project looks, the drums will always be low priced and low quality Asian shells that have been fitted out with components and cosmetics that will cost you much more than the drums could ever sell for if you ever decide to sell them. Have fun with them. I have a project set that will never recoup half of what I spent on it while having a great time cutomizing the drums to my taste.
