yea upon further review you are defiantly correct.  what caught my eye 
was the tape drive and the ability to expand the disk array.

yea i've kicked around the idea of disked based backup, but i am going 
to try to offline alot of my cruft that has built up over the years.  so 
i'm thinking tape is probably the best bet for that.  i've never had any 
issues with DDS myself, but thanks for the heads up.  if i end up with a 
dds drive i'll have to choose my stock carefully (and storage for that

<quick plug for bacula>
yea i check out flexbackup looks pretty cool.  i've fallen in love with 
bacula myself.  seems to have the best mix of higend stuff (sql catalogs 
etc.) that i want to work with for my own purposes and it quite easy to 
setup.  anyway i would definatly suggest bacula to anyone, it is 
actaully a very nice package.

So after looking around on ebay for a while i think i have a general 
idea of where i'm going to go with this.  it's either going to be a sun 
ultra 3 (in which case i will get the required scsi cards and external 
AIT drive which i have a line on) or an older compaq which has a builtin 
tape drive/raid etc...thanks for the input everyone it's actually 
helping me narrow down what i'm exactly looking for.
