In terms of quality, I would stick with the Amiga 2000, with a German-made 060 board and a GVP Spectrum or Picasso II graphics board. As far as the bus speed, there is not that much difference between 24-bit and 32-bit. If you want speed and high resolution graphics, get yourself an AmigaOne. Why mess around with the poorly designed and lower quality Amiga 3000 and 4000 computers. You can get an AmigaOne computer for less money then you would pay for an Amiga 3000 with 060 board and Picasso IV crap. Let me think: Picasso IV or ATI Radeon? 68060 or a powerful PPC processor? Amiga OS 3.9 or Amiga OS 4.1? NO BRAINER FOR ME.
Let me clear things up for you guys: The highest quality and best Amiga model ever produced is the Amiga 2000, this is a fact not my opinion. So, if you have an Amiga 2000, keep it. Never trade it for an Amiga 3000, 4000, or 1200. Also, keep in mind that the Amiga 500 (the Amiga 2000's little brother) is the most popular and number one selling Amiga model of all time. Never trade an Amiga 500 for an Amiga 600 or 1200. If you are puffed up with ego, and you want an Amiga that is really fast and has high resolution graphics, buy an AmigaOne with OS 4.1. It is just that easy boys and girls.
