Welcome scientist
Personally, I would not buy a new A1200 from Vesalia for 150 Euros. I would look on ebay, or in newspapers,etc for a used one, which should go for something like 20 pounds (about 30 Euros) or maybe a little more. This would allow you to start playing around with the Amiga again without spending lots of money.
As far as the 'new amiga' goes, well that's a minefield. PERSONALLY, I'd wait and see how the various new Amiga solutions turn out before buying...
:-? :-? :-?
--edit--
Sorry, I didn't see this part:
Buy an A1200 remember the old times and from time to time start the upgrade to tower and finally to PowerPC processors
Well in THAT case, its debatable whether its worth spending lots of money towering an A1200, accelerating etc at this stage... I think I would go for a towerised A1200 with accelerator if I could pick it up cheap, but otherwise its too expensive for an essentially ancient piece of hardware
It might be worth looking at the webpages of the various OS/ hardware solutions, but I'd think hard about which solution, and don't be afraid to wait to another 6 months to see how it all unfolds
