Just FYI, ersa-shop.com is
not Ersa itself, it's a reseller (Bräunlich, a reputable vendor I have used before, ordered via Amazon). On the stations themselves, Amazon.de is cheaper, but on the accessories (tips, the little tip holders, brass wool, etc), Bräunlich has much better prices, if you order a few things at once to make the minimum shipping cost worthwhile.
I love my i-Con Nano, but I kinda wish I'd spent just a bit more and gotten the i-Con 1, not because of iron performance (it's fantastic), but because of the user interface: I think I'd prefer the rotary encoder and backlit display (and front panel power switch!) to the up/down buttons, non-backlit LCD, and rear power switch of the Nano. Admittedly, another €100 just for those creature comforts is a lot. :p
Arko, if you're considering spending a fair bit more, depending on where you are this could make sense: someone here in switzerland is selling a new in box (apparently bought years ago but never used) Ersa i-Con 2 station with the Chip-Tool SMD tweezers (in addition to the standard i-Tool soldering iron), asking CHF550. I'd love to get it myself but my finances are absolutely tapped out right now.
