SCSI backup solution

[Liberty Young]

Working for a small business, what would you all out there recommend for
a backup solution? I'm leaning toward Tape backups, but the solution
needs to hit these things: 

1) Be easy enough for somebody at the end of the day to just pop out a
tape, pop it in, and walk away. 


2) modestly priced. 

3) Enough Linux support already there so i can get it working within a
weekend. 

With these in mind, what Tape Drives should I buy? I don't have a SCSI
capable Server yet, but i believe that could be fixed with a pci card.
Any suggestions for one of those?
