Dormobile roof hinges

[thejinx]

Looking on Dormobile site. Roof hinges £30. Not a bad price but any ideas where I can get a better quality hinge or for same price? Are these hinges top quality or can I get them from B&q cheaper?

I got mine from the campershop in Upton about 7 years ago and still going strong ( http://poptop-parts.co.uk/dormobile.htm" onclick="window.open(this.href);return false; ) the hinges are specially shaped and made out of brass (I'm assuming your talking about the main roof hinges?)
