Welcome!!!
One week ago I was new in this forum, and I can tell you, that in Amiga.org there is very helpfulness air!
They help you everytime ;-)
Reading the forum, and asking some things, I understund that better choice for return to Amiga style, is A1200.
As I can see, you are European as me (Italian), and you can get a lot of A1200 from German people checking on eBay.
Or you can get new from web sites.
....this week I've get A2000 :-P on eBay...
And remember:
"Only Amiga Make it Possible"
Have a nice day, Angelo. :-)
