We're already up to $340... so making it yourself is not an enormous cost saver... however you can have the exact setup you like and if you are flying North Kites like me you don't have to put up with shitty bars and crappy lines (I do like their chicken loops and depower cleats tho...)
I think your costs are too high.
composite bar: $30
new ozone megatron chicken loop: $35
leader line, chicken line etc: $25
naish swivel/safety : $50
I get $275 to make a brand new bar. I have three bars I have made myself out of various parts, it's definitely cost effective to make a bar, you save about $75 over last year's 2012 naish bar for $350.
By contrast making a brand new kite is not worth it, if you try to purchase enough teijin technoforce t9600, dacron, tubes to make a 12meter kite yourself it gets up to about $800 new. Unless you can get a bulk price on the canopy material you are just making a kite because you like making stuff.
The north bar is really high quality but it comes at a price.
