Faxing from AS400

I have been asked to review replacing an existing Fax Server (a
separate pc unit that reads as400 spooled files and has 
software on as400 to manage traffic), with IBM's 
internal fax cards and software for managing. This site does 
200 - 500 outbound faxes a day over 2 lines, and weekly a batch 
of 2,500. I am totally unfamiliar with the IBM software and looking
for comments on how easy to run by itself, daily reports or screens
of failures, and ease of use to resend, reprint, use  both *scs & *afpds spools,
merge logos & forms with spools, etc. 
Customer upgrading to i5 and this fax server is older 
and needing an upgrade for a hefty sum (over 12k). 
Approx 15 rpg programs sending faxes.
