Why only these two choices? For probably thirty years, I have always used one of these (melitta coffee filter holder) for making coffee while camping:
For a crowd, I will use a #6 cone and make coffee in a thermos. For just me, I will use a #4 cone and make coffee right into my mug. All you need is boiling water - which DW uses for tea also. These funnels use the same paper filters that you use for a drip maker. When you get your coffee ground, have them grind it 'for melitta' (somewhere between espresso and drip - an espresso grind will clog the filter, a drip grind will let the water pass through too quickly).
I've had some trouble finding the cones in local stores, but here is a place that appears to sell them on-line:

I think
WalMart might have them too.
