What accessories with DP2M?

What accessories should I buy if I pick up a DP2M?

I can see the AC adapter and the Close-up Lens AML-1 being useful.

What about a view finder. Is there one better or more reasonably priced than the VF-11 that works as well?

I've seen discussion around a grip as well. Any conclusions on that?

I gather the software that tethers the SD1M doesn't do the same for the DPM series?
