if the price it raised i doubt it's due to cost of raw materials but more so as more people jump on the band wagon. even at $149 i'm positive the company is making money and at $200 they're just making that much more. now i'm not saying anything bad about the company it's just how business works.
here's a good exmple, alpine iva-d310 hu cost what $1300 for a regular guy to buy one. now i know someone who has a shop and they paid $250 a hu (they make $1050 every hu), and of corse alpine will make their money even at $250.
