SCSI backup solution

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?
