I’ve added a link to Richard Johnson’s DCC Concepts web site to the links page (thanks for the suggestion Peter S!). DCC Concepts is a local supplier of digital products, tools and components for modellers, by modellers — Richard is an active modeller at AMRA(WA).
If you’ve never had a look at Richard’s site, please do. Not only does he have a lot of information about the products he carries and sells, he also has a lot of useful links and general information of use to all modellers.
Update (1/3/08): Peter S. has pointed out that DCC Concepts are now in Naval Base (not far from the US Model Railway Club of WA), not Canning Vale. Apparently the building they were in was sold and they had to vacate.
