Adit600 with 48 FXS = ~USD$500-600 on ebay
TE405P = USD$1500

Two Adit600s give you 96 ports and the TE405P will let you grow that to 192 
without breaking a sweat for $2700.  You can save $500 by using two T100Ps 
but you won't be able to get past 96 ports without more Digium hardware... 
and they don't bus master either, but not sure how big a deal that is.  :-)

Remember 96 ports translating from slinear -> GSM or iLBC or g729 is going to 
require some processor power.  AND you're talking the backbone of your 
company's phone network too.  At the very least I'd be looking dual Xeon 
(mobo quality speaks for itself) with SCSI RAID1 (HW or SW) and dual 
redundant power.  Supermicro makes such a system, I think 1 proc, 512M ECC 
RAM and dual 9G drives was just under USD$1200.

And if you're playing it safe, you'll have TWO TE405Ps and an entire extra 
Adit600 chassis + power supply + at least 1 T1 controller + 1 octal FXS card 
lying around. 

Ask yourself how much fun it will be to have a dead card/power 
supply/motherboard/channel bank chassis and the entire phone system is down 
while you're sitting there with your thumb up your arse because 5 minutes ago 
you were bragging about how much money you saved by not having the spares 
handy.  :-)
