Thanks Dean,

At the moment I was thinking more for the less important parts - motor mounts etc as it will make life a lot easier having a reliable local source that I can nip into to get the occasional piece without any postage costs.

I've seen AW mentioned in several build logs & have them bookmarked already when it comes to the important parts. It seems the narrowest width for the Ecocast is 100mm which may well make a design decision or 2 for me as well...although this could be an issue when it comes to mounting the Y rails on top/bottom of the gantry?

I assume that 5mm Ecocast will be ok for the rails to mount to?
