Thank's for the recommendations.
I went here looking for a private soldering station, I previously only have experience with Metcal's [SMA factory repairs] and Weller's [various]. I couldn't wait for your review (is it here somewhere?) so I basically copied your list minus a few conical tips but added the power-well 2.3mm and the 10mm. Adding support for the tweezer tool or air tool looked tempting but were too pricey for my use-case. I'll just settle for a heat gun and "manual" tweezers instead.
I just bought a Ersa I-Con Vario 2, with hot air and Vario Tweezers. Actually I was only looking for tweezers, as I already have two I-Con Nanos, a noname throughole dessolderer and a Aoyue 852A++ hot air gun. As I am really happy with the Nanos I wanted to stick with Ersa. So I looked at the I-Con1, but you can't use the Vario Tweezers with it. These tweezers have two times the power of the non Vario tweezers (2x40W instead of 2x20). So I wanted the I-Con1V, but the I-Con2V costs almost the same. Thinking about spending 700 Euros, I thought it would be a good idea to spend a bit more and get a good airgun, too. So I ended up with the Vario 2.
This unit is really great, the tweezers are fun to use. Because of the high power and a temperature sensor in each leg soldering is on a complete new level.
The air gun is also great, much smaller than the Aoyue. The temperature is spot on and has more than enough airflow and power for me, and heats up really quick.
My Vario doesn't have the vacuum pump installed (I couldn't justify another expensive "upgrade"), but I found a X-Tool Vario and a CU100 pump on ebay for a really good price. So now I will work only with the Vario and the Nanos.
My advice for someone buying a new station is getting a Nano if you want good quality for a good price. It has the same handpiece like the I-Con, but with only 80W and no automatic wake up. But usually it wakes up when you take it out of the holder and clean the tip (it recognized the temperature drop of the tip).
If you want to be able to upgrade with tweezers, throuhole desoldering or a high power handpiece later on, get the I-Con2V. IMHO the Vario tools are better than the old ones.
If you are crazy like me, get the Vario 2 or 4. I opened my Vario 2 today and think you can upgrade it with the internal vacuum pump (saw it too late, my external CU100 pump is already on the way). The pressure sensor and cable connector needed for the pump are installed on the mainboard and I think they use the same firmware for all versions (Vario 2 and 4).
