Help choosing DMM with PC datalogging.

Nah, definitely only PC datalogging. Memory in the meter isn't needed at all.

I have not played with that one, but Protek meters have a reasonable rep, and the older 506 model has been around for a real long time and was a decent reliable meter for the price (with a few quirks).
Protek isn't a bad choice.
But like someone else said, someone on the forum got an Amprobe 38XR for $65 on ebay, which is remarkable value.

In either case download the software and play with it make sure it does what you want. Flaky PC software can be a showstopper with these PC link meters.

I already have, and it was the one reason I hadn't already ordered the protek.

No vista support, max sample rate of 1 second, and no way to save graphed information. Although, that just could be because there wasn't any data yet.

I'll look further into that 38XR.

For a while now I have been relying on my HP 3456A multimeter.  Its accurate.  Of course it is old, but I don't think I would let it off my bench.  Thanks to eBay I will have a 3458A too.

If you need a VREF all of the Mfr's out there, ST, Itersil, OnSemi, analog, national, linear, Maxim, Microchip. 

I use this device:

Mine stays pretty near +5v DC.

But, I use the GPIB/HPIB funcitonality with my NI PCI card and LabView.  Of course the setup is not really that portable but it gets good use.
