I'm looking for more local sources for materials. I have a good local steel yard 5 miles up the road that i've used several times before - so am happy to use them for the framework, but their aluminium stock is low, a bit battered & unreliable.

I've found that there's a branch of Blackburns Metals not too far from where I work - does anyone have any experience with them as a supplier for aluminium?...quality & prices ok?
