So, just looking at the general pricing, at a site I like. What is good is that they have a user support forum (http://forum.analogmetric.com/). Then they tell you what component brands that they use:

Remote Control ($59): http://www.analogmetric.com/goods.php?id=1132
JP200 ($143): http://analogmetric.com/goods.php?id=996
Power supply ($99): http://analogmetric.com/goods.php?id=1016
Input Selector ($19): http://analogmetric.com/goods.php?id=1928
Transformer ($49): http://analogmetric.com/goods.php?id=1126
Choke ($49): http://analogmetric.com/goods.php?id=243
10 Gold RCA ($20): http://analogmetric.com/goods.php?id=476
Chassis ($80): http://analogmetric.com/goods.php?id=646

Total: $518.

This costs more then the 'Kit', but it has much better compients (like a motorized volume, gold connectors, etc, etc.
