If you keep it very low, there could be someone here (not from Europe) who wants to buy a kit.
Because in Europe you can get the analog  JBC BT-2BWA with Handle & 2 chisel Cartridges for 249,-  Euro's. Without the Handle and the 2 Cartridges you pay plus/minus 150 Euro's. The station is new and fully factory warranted.
I'm personally more interested in a analog BT-2BWA or digital CD station hacked to use with the 2 JBC TweezerTools.  ;)

Ok, it's analog but still tempting.

It seems very complicated. I have done solder stations with A1321 handles (4 wire, with thermcouple as a temperature sensor). Power comes from a laptop power supply (20v), and NE5532 as the thermocouple amplifier (with some avrs having 20x / 40x adc, you don't need that amplifier at all). No display however, other than an RGB led to indicate status.

Temperature kept within a 1c or so.

I may build one with 4-digit led display just for fun - the firmware is already written.

It is not complicated. It's only a prototype, so it looks the way it looks. Esentially it's 2 MOSFETs, 3 optocouplers, an opamp a microcontroller, some shift registers, basic power supply and a handful of passives.

Dunno if you're joking or not, but hot tweezers are from hardware standpoint two separate tips :)

No, not joking.  ^-^ Read more carefully what i said.
 And maybe you can make your controller compatible with the JBC Tweezer-tools, or must i buy and use 2 separate controllers from you for one tweezer-tool (with 2 tips)?
