So little love for the 1200?
With the humble 1200, you get:
AGA (you can use various tricks to run old software on your 1200, but nothing will get an AGA title to run on an ECS machine)
2 megs chip RAM built in.
A wealth of reasonably priced upgrade options for processors and RAM today.
Hard drive interface already in the machine
PCMCIA interface, making for extremely easy file transfers and networking.
On top of that, back in the day, the 1200 was quite affordable, even on a budget. Sure, a 3000 or 4000 was great but you'd pay through the nose.
