You have missed the one logical,reliable machine. the A4000 or 4000T. other than caps, this is the full 32bit machine with proper z3 expansion bus,and unlike the 2000 with slow zorro2,you get better speed on gfx cards etc. I love the 2000 but its not the most logical machine to do with 060 since zorro2 is so slow(2-3MB/s). Unlike the 1200 it wont be dongled to death(generally) and need a immediate psu upgrade etc. A fully expanded 1200 will still be slower than the full expanded 4000 generally.
I love all amiga's but it still puzzles me why people build on the 1200 as a base.Its not cheaper in the long run and many times not as reliable,and certainly not as fast as the expanded 4k. I have probably opened pandoras box saying this 
just curious...an sorry to interrupt ..your coment about a4000 would be faster than a a1200 ...question..if ur just using the aga chipset an the cpu is the same an memory is the same ..would that be the case?
with a graphics card id agree ..with aga why would it be different..
