The component range used to be based on the Australian electronics magazine articles, which was good. The component range is now limited to some really odd parts and are quite expensive. They are still good for one or two bits on a sunday morning. DSE do supply trade, if you're keen, but from what I've seen, still relatively expensive. They seem to have most bits in stock and deliver the next day.
Prices are medium retail for low volume, high for higher volumes.
Hi-Q Good service, prompt delivery, reasonable pricing. Connectors and hardware type stuff only. They have a good range of plastic hardware components. Supply a range of connectors and enclosures. They have a good PCB mounting plastic rail product.
