This is heavy weight stuff.  I would like to put your link to GOLD REFINING FORUM - GOLD REFINERS HELPING ONE ANOTHER mining and geochemical section if you aren't there allready?

There are very strong opinions about XRF.

I've used a stationary XRF machine before.  Its easy to use and give great results.  You need to prepare crushed samples and the machine gives great results. 

We were using RC drill samples so they were already crushed.  It gives you a breakdown of all the elements in your sample.  Just like a previous poster mentioned, its like an instant geochem assay.

I don't know how a portable one would work though.

Yes sample readiness is important XRF Sample Preparation Methods/Procedure | Metallurgy Testing & Research

I personally just pulverizer + point and shoot.

Excellent thread and input.  I had some rocks sampled recently by XRF and was surprised by the results.  It was only done on the outside of the sample and perhaps it should have been on crush instead.  I have also looked around online for my own machine and the darn things are expensive, even used.  I asked a couple of distributors about maintenance and did not get a straight answer.  Online, there seems to be many from China, which to me is a red flag that it might be a knockoff or some of the ones for sale might be knockoffs.  I would hate to spend thousands on something that is not real.
