The Dove MacSNAP was both popular and well put together. The SCSI cable that pokes out through the security slot is fairly well implemented (ie not as well fitting as an official upgrade might have been if it existed). My 512K with MacSNAP was sent by post for 100 miles, and the Killy clip stayed in place.

The accelerator/RAM package that I would most like to own is the NewLife with external monitor support. Magazine reviews in the late 1980s were very positive about this one.
