I think what you would need to look at first, would be the voltage of power systems in Romania. My partner is from there so I'll ask him when I am speaking to him.
IF as in many parts of europe the voltage is 220 ( and not 110 as it is here in north america) then you'll need a machine that can function on 220 power. There are a few options ( many of the recent apilus have switchable power supplies) but you'd probably find it much more economical to get a machine out of the UK I believe the sterex machines are quite popular for european use.
As for learning, you can get Mike Bono's book, or electrolysis thermolysis and the blend by Hinkel . The best source for advice however is right here, there are a lot of very talented professional electrologists here and I found them very helpful in learning .
Given what I know of Romania ( not a ton except a few things my partner has told me), I can completely understand why there wouldnt be any electrologists nearby. This would be the type of scenario for which I do definitely endorse DIY use. I would still stick to blend electrolysis however for safety reasons.
