paid 275 for mine. Flawless, not a single bubble or dust bubble. The cut was perfect minus in the back window there is a tiny 1mm gap right at the edge.
Get quality tints and you won't regret it. The shade is consistent and it doesn't look "aftermarket" at all. Got it done May 2012 and not a single bubble or any sign of turning purple.
If you have dust particles, id say send it back and get them to redo it.
