Ebay. The seller is named 'troyexporter'.
Regarding the wand connector. Yes, it is true. Once the switch is on, one of the pins potentially is live. 50/50 chance, as the AC plug in the EU (CEE 7/7) is not necessarily polarized. If you're in France, you should be a bit safer, not so in Germany.
I added a big fat "! DANGER HV !" sticker next to the plug. Hopefully it will prevent me from being stupid. Maybe I should get an isolation transformer - just in case.
On the bright side, they could've wired it up worse, i.e. a permanent (unswitched) connection to the front-side connector. Luckily they didn't do that.
