I went down the same path as you...
I had a decent-spec A1200, then picked up an A4000 & A3000, but found it frustrating to get things set up just the way I wanted.
Then I sold my real Amiga hardware and installed all of my old drives and software on WinUAe and have never looked back.
I now have the ultimate Amiga - running 16 bit AHI and a 24-bit Full HD Workbench...
It's far faster than any real Amiga hardware, with less compatibility issues (WinUAE is almost infinitely tweekable in that sense) and far greater reliability.
I also have the added advantage that I can boot into WinXP or Linux Mint...
Mike.
