Glad you found your way to the forum. I think the advice given has all ready surpassed anything that I could say. I sugest getting some good email contacts and before purchesing anything get an opinion from some one who knows there stuff.
I also would like to say that sometimes getting something shipped from the USA can be cheaper,as I have found out recently.
