I have a better tip. Invest in a JBC CD-2E and a couple of different tip styles. I have used Metcal before (they are good and I never had tips not heat up), but the JBCs are a whole new ball game IMO. I have also used Pace (great), Hakko (crap), Weller (good), Royel (who?), and a range of Chinese made ripoffs (all crap).
An engineering friend who bought one of these JBCs reckoned the irons and the tips are an order of magnitude better than anything else. I was a little sceptical of his claims but I bought one for work. I was so impressed I then bought one for home. Never looked back. (In Australia, Mektronics and Oritech have them on special occasionally and to seal the deal from one of these suppliers, I asked for and received an extra free tip and free delivery on top of the special price.)
Quality is remembered long after the price is forgotten. I wish I had this mindset over the last 30 years as I collected a plethora of cheapo low quality spanners and sockets - a big mistake. Recently I spat the dummy after a socket stripped when I was replacing my car's brake shoes. So I invested in comprehensive set of quality sockets and spanners at a one-day 50% off sale around Christmas. Cost me a few hundred dollars which hurt the hip pocket nerve. They were so beautifully engineered, I even confessed to the wife what I had bought without approval. As I use then, I realise what I was missing out on over the last 30 years. Soldering irons are similar to quality mechanics or carpenters tools - invest in the best upfront and reap the long term benefits.
My old iron at home is a Weller which I bought 38 years ago. I used Weller and my wife used Wella. These days, I use JBC but the wife still prefers Wella.
Top quality tools are worth the extra money, IMO.
