Have you considered external console servers?  in my experience, 
they are radically cheaper than the internal stuff.   A 48 port
OpenGear brand terminal server is $1500 or so.  per-port, that's about
an order of magnitude what you'd pay for a dell DRAC.  Of course,
if you are running windows and need a KVM over IP, this doesn't help,
but serial consoles are /vastly superior/ for linux use.  

external serial consoles, in my experience both personally and
working on Yahoo's search cluster, are much more reliable than 
both the HP ILO and the dell DRAC.  (the hp ILO is marginally
better than the dell DRAC, but it is still garbage compared to
an external serial console.)

It was pretty cool;  at yahoo we actually had our perl guy write
a script that connected to each serial console (and we had many 
different types of both external terminal servers and internal,
IP access able serial consoles)   and dumped the console log
on one server.  I could sit in one place and use grep to fine
all the MCE panics and all the bad drives.   

Every 'server class' motherboard I've seen had the capability to 
redirect BIOS console over the serial port, and of course, you can
do the same with grub and Linux once the box boots.
