Most of my risers I just paid a few bucks each for on ebay. I did however buy a $25 riser with molex from cablesaurus. It works great, and the shipping was fast, but $25 is still a complete ripoff.
Supply and demand?
supply and demand would only justify his pricing IF there were a LIMITED supply, which is clearly not the case.
actually supply and demand is a factor...
demand is low... primarily it is only used by miners.
supply is also low... each molex connector is soldered on by hand which raises cost.
then it boils down to how much do want to gain in profit, how much time does it take to add a molex connector.
i add my molex connectors differently so it takes me at least 1/2 hour just to do 1 cable.
if i were to sell them i would be charging a lot more since i think my time is worth a lot.
but i don't sell them... I think I'm rambling now.
