I recently bought a Yihua 898D 2 in 1 and I'm quite happy with it.
It arrived with spare heater cartridges for the soldering iron and the heat gun. When I opened it up to replace the European power cord, it seemed to be quite well made. It gets up to temperature very quickly and (to the limit to which I can test it) seems to keep a stable temperature.
Delivery was about 4 days and from the US, not China. Total cost $A112
Here's a link to the eBay sale.
thanks, also geoffs, your link isn't working for me
amyk, thanks, but if that isn't likely to be an issue, i would really like to save my money, also, the postage for two separate units, although it would probably be less if they were packaged together, would likely be worse that it already is(45US on a 55US product).
So what im getting out of this is: getting a cheap one will do just fine(assuming I don't want a rock solid product that will last 100 years)
