It is not odd to find prices that are lower or equal to what it would cost to make snakes. Once you factor in your time, the snake cable and then the connectors (which is where the majority of loot goes) - it becomes pricey. Figure roughly .35/ft for Canare cable [.68 or so for Mogami], $2 per connector (and also remember if you dont have solder, iron, stand, wire cutters, wire strippers, etc. you have to think about buying those).
The problem with Neutriks normal connectors are that they contain plastic which isnt as strong as steel/metal. That said - if its going to be for studio use, either Switchcraft of Neutrik are fine. If you are making the cables yourself - Id go with the latter.
