3) - Depends on your demands: An A4000 with A3630 or A3640 might be cheaper than a fast accelerator card with ram for an A2000. So if you just want to have a fast powerfull Amiga, you should look for an A4000 or an A1200 in a tower-case. The accelerator boards for the A1200 are much cheaper and easier to find than the ones for the A4000.
My A4k gets alot more use than my A2k, but I whole heartedly agree with the lack of accellerators for it. C'mon folks, throw us A4k lovers a BONE!
