In the US, Redco Audio has the best price for the Mogami that I've seen. I got it for $0.64/foot, divided by four = $0.16/foot per conductor. I just buy most stuff from them. For the SMC connectors, eBay has some seriously inexpensive ones, but I only have experience with HiFiMAN's. I've read a few times that Double Helix has a slightly different SMC connector that is supposedly easier to solder. I had no problems with the HFM SMC connectors. The eBay version(s) may be worth exploring. I probably would have, if I'd thought about it. I like Paracord Planet for the 550 I use as a sleeve. Check 'em on Amazon, as it's easy to go through all the colors and patterns, and one vendor may still offer free shipping. I also got a heat shrink variety box from Amazon, but you may want to explore 3:1. I used 2:1 and it was good. If you remove the outer sheath and the inner copper shielding of the Mogami, you end up with a ridiculously light and supple cable. I think the total cost of my 10-foot cable was around $20, more than half of which were the HFM SMC connectors.
