You're better off just getting the brackets for the hoops and a deflector and be done with it... Not sure how much difference the full kit will make... unless you want it purely to be complete? It's probably £150 for just the deflector and brackets... vs £300/350 for complete kit.
Think the exact same one (linked from gumtree) is on ebay if you wanted it posted.
Dang that is cheap even once converted to US $. aprox $480. The cheapest I have found for just the middle deflector (new) was $410 only. No other parts included ie: hoops, hoop screens, etc. If they do shipping might give it a go?
