^ I can attest that good cables do cost in materials.
I make pretty much all of my own stuff.
All my recables are done by myself and the costs assciated still isn't that cheap. When you start dealing with exotic materials or even just high quality ones, the prices are pretty high for all the pieces of the puzzle. Then factor in time, soldering, and matching everything. Then, the finishing. If you have experience and time on your side, it is a good venture. Otherwise - leave it to the big guns.
BTW: Not many manufacturers remove the other pins. I can say this with confidence on the recent Microshar LODs. I was appalled at how it literally fell apart and left me to fix it. It was not abused and just did not fair well. There are other manufacturers doing the same.
Personally, I make my own LODs. It takes a steady hand, patience, and experimentation. Those pinns can be killer to solder at times and can require some finesse. It gets easier as you do more of them though.
