Soldering Iron is an important tool. Good advice would be to buy a soldering station with temperature control and a good selection of tips. I've had really good Soldering Stations - like "Royal", but they don't make them anymore. That soldering station is almost 30 years old and STILL works.

OK - Dick Smith have a decent range - more than Jaycar - but it would be worth looking at both stores to see which one you like.

Here's an entry level station;

This station looks like a copy of the Weller Station

eBay Stations are more "hit and miss". At leat with a store you can buy tips etc - which is great for the hobbyist.
