TekMagic A2000 060/50MHz
I'd stay clear of the TekMagic if possible and get the Blizzard 2060. The TekMagic needs the three finger salute on software resets in order to boot and the SCSI controller can only boot from FFS partitions.
It is something you can live with, but can get annoying in the end. It did for me so I decided to ditch the A2000. The SCSI controller on the TekMagic is super fast though, so it's not all bad.
