For quality and accuracy ATA ranks up there in the top. As for ease of assembly, it all depends on what skills and the amount of patience you have. ATA's molds are crisp and everything pretty much lines up, however, ANY armor you buy requires a certain amount of trimming and tweeking. NO armor is one size fits all. With you being 130, you will need to trim. Price seems fair.
The main suggestion is view the build forums and ask questions. Do not just start cutting willy nilly. This is an investment in your time and money but with a little skill, patience and a lot of questions, you can make yourself a wicked set of armor.
