Huh? Where's the A2000 accelerator? And I mean accelerator, not some underpowered completely useless 020 or 030? My last achievement was a used Blizzard 2060 which cost me 2/3 of a new Sam440ep. So much about "affordness".
Look around. Amibay, eBay, etc. More 2060's, 1260's, and PPC cards for the A3000/A4000 the last couple of years being sold than ever it seems. 2060/1260 still in the $350-$500 range. But yes, the PPC boards are going for crazy silly prices.
And hell, the "measly" 020/030 will probably forever be in more peoples hands than X1000 + Sam systems combined. Don't understand what's "completely useless" about either chip??
