So far skip’s offer of $3000 seems reasonable.
I know apilus does have a european sales center, so assumably there are some of those kicking around in the european market. I checked the TES website and they do have the Elite sprctrum without air for $2749($3124 with air option) but that would be a model made for north american power systems. They have a shop and could easily change a power supply I should think, but to sdo so and come in anything under $3000 with a professionally changed powersupply and shipped to germany I dont think they could do.
Here in Canada I can lay my lands on a number of epilators by looking on kijiji or craigslist, or even ebay for under $1000. However one of the professionals on this board, Beate Ritzert, practises in germany and may be able to tell you where would be good place to look for one on the used market, that would be wired to European standards. Apilus does sell to the european market, but I think a platinum goes for about $5000 .
You may also want to quiz Beate on the regulations for ggetting into electrolysis in Germany. While I can go along with your idea of doing yourself as a DIY project then practising in your spare time, and have done so myself, I understand from Beate that Germany has some restrictive laws about who can do electrology so she could best fill you in on these.
Seeing a professional can quickly add up to more than the $3000 you would spend on a machine. But also too can the costs of putting extra equipment to practise professionally or semi-professionally. Treatment bench, good optics, a tested and certified autoclave, all are required to do any level of professional work and all are fairly expensive to purchase.
I have never regretted learning electrology. I’ve enjoyed it immensely. But even as this boards arguably most successful DIY’er I would still tell you it is a skill that is exacting and takes a while to learn to do well.It demands you think and use what you know of physiology. I am the first to say that such a project is not as easy as I may have made it seem at times.
