Hey, Welcome to AO.
As said before you have a fue options as to how you want to go. An Amiga 3000 tower an A4000 desktop or Tower and the A1200. These all will give you many years of enjoyment.
The A4000 is harder to find and more costly but well worth it because you can put a Graphics card and farly fast eccelorator in it The Cyberstorm PPC would also let you run some PC software as well but in my opinion its not worth it. The Cyberstorm MK II or III 68060 50 mHz. is a very good option.
It would be almost impossible to find a new A3000 or A4000 but there are some A1200 available.
