Hello,
well I started like you and I have bought in the past months RGB<->VGA adaptor but did not achieve anything yet maybe I need scandoubler too.
But getting into A1200 world I had fun connecting external Cd-Rom drive using Idefix Express and bought a wireless card to surf the web.
Well I didn't use the Amiga at 100% bcoz need a lot of hardware and time reading forum and attemps too.
But I think that is worthy and would give me a lot of satisfactions.
If you have passion, a bit of time and money it's worthy and have fun!
