ok, first of all thx to all you people reading this post. I will answer some of the question now.
1, yes $50 is in Can.
2.if you can make it for $15, good for you!!! but consider now I'm make them in a lower price and install it for you, I think $50 is not that much. since free installion sounds kind of funny here isn't it?? but if you think is too $$, that's ok!! ;-) what about $70 for set of 7 include installing?
3. thx for giving me the link of where I can get wires, but one thing I want to point out is that include hadling and shipping, would it be over $50 after i put everything together?? I'm not saying you are wrong, but you have to understand that I'm in Canada, if I get stuff online and shipping to here I need to pay more. Again free installion sounds kinda funny here isn't it?
P.S. if you people think that it is too much then is ok! I don't mind! but I guess there's actually some people think that it is worth it! Also you could always go for $70Can for set of 7 too!! so if you people don't like it, why not you start making them for others in a even lower price??
