Help me 2Rank my RAM choices

What are the advantages/disadvantages of using 2Rank DIMMS as opposed to standard DIMMs?
I'm pricing out an HP server for work and I have multiple options for adding 4GB or PC-3200 DIMMS. I can go with
(a) 4x1024
(b) 2x2GB 2Rank DIMMs -- for $130 more than (a)
(c) 2x2GB -- for $1050 more than (b)
Obviously, the price and slots used (out of 6 available) ratio favors (b), but I'd like to know if there's some hidden reason why it's so much cheaper than (c) -- or why (c) is so much more expensive. Wikipedia's DIMM article doesn't give me much useful info on the subject.
(I know I can get memory cheaper from 3rd parties, so no need to mention that.)

One other thing to consider for server applications is whether you'll be going for ECC memory, or non-ECC. Your choice may also depend on what operating systems and applications you'll be using, since if you are sticking to some Windows variant that observes the 4 GB memory space limit, your plans for adding additional memory later may not mean much, unless you also plan on moving up to 64 bit.

This link explains multiple ranking. I can't see any reason to rule it out unless it significantly increases latency.
