Well, the RE-850 was the upgrade path for the RE-400. For a 
long time, the default RE that shipped for M7i/M10i bundles 
was the RE-400, which allowed Juniper to sell the RE-850 as 
an upgrade (more $$ for them).

Now, one would be hard-pressed to buy the M7i/M10i with the 
RE-400 instead of the RE-850, but many bundles still sell 
them like that, and most customers will prefer to pay less 
money than more :-).

The RE-400's are okay. You just need to watch out for these:

	a) Make sure you have at least a 1GB compact flash
	   drive installed in there. All Junos since 9.0 has
	   required 1GB of space on the compact flash
	   (although I've been able to install a copy of
	   Junos 10.4 on a 256MB compact flash drive,
	   something I'd only recommend to my competitors).

	b) Have a hard drive on standby; they tend to fail
	   quite a bit. 

	c) Install the full 768MB of DRAM, especially if you
	   plan to hold a few full BGP tables. However, this
	   won't scale as your BGP needs grow.


Cheers,

Mark.
