Trust me, go for the i-Con nano.
The RDS80 is ancient technology, heats far more slowly, not ESD-safe, and most annoyingly, the cable between the iron and station is really thick and stiff.
I have the nano and it's awesome. It heats super fast, tips are cheap and plentiful, and the cord is thin (not as soft as on some higher end stations, but still very soft). The only thing that sometimes makes me wish I'd bought the i-Con 1 instead is a) lack of LCD backlighting (which the RDS80 also doesn't have), and that the nano's 2 buttons make for a very sparse user interface. (You can program it via microSD card to either have three presets, or to have free temperature control. But you can't do both.)
