To pay $200-$300 for A1200 with an 030, scsi and 8-16 mb RAM is not crazy: you can play any Amiga game ever made, you have some good graphics software like dpaint, ppaint brilliance, lightwave, good music software like soundstudio, protracker, bars and pipes, good multimedia software like Scala. This means you can have a lot of fun playing some very playable games and you can create some semi-professional graphics and music and put it all together to play back on your tv or digitize the ouptut on pc as MPEG. Great for cartoons with sound, and much easier for a home user to do than PC equivalents.
But what i think is crazy is paying 1000's for a tricked-up "high-end Amiga" whose purpose was to basically display 24 bit images, 16 bit sound and mpeg1 quality video, you know stuff that the native chipsets don't offer, but PC hardware is MUCH better at, even 10 year old PC hardware. Some are curiouys to see os4 but really its about 10 years too late..
