looking for some advice or a recommendation for a new soldering iron. I recently broke my 30 watt iron and looking to replace it with something a little better. im looking for a stand alone, not a station, because I put It in my back pack and take it to work with me. ive been looking on ebay and radio shack, but it seems like everyone is using steel tips. why do they even make steel tips? solder doesn't stick to steel. ive had bad luck trying to tin steel tips. what I was using before my iron broke was a thick piece of copper wire ground to a shiny tip that tinned very nicely. it will be for general purpose and the ocassional small stuff like soldering usb jacks. thanks!
