This should be considered at > purchase phase. Consider ALL features. Weight them by whatever scale YOU see fit for a portable potentially pocketable field instrument for general purpose use. Don't forget to include the surprisingly complete filtering modes available (weighht themas you wish), display capability for size (weight as you wish) and all the rest. Report you weighting factors to allow comparisons. Divide your own weighted assessment by $US35. Report result. Anything that comes close in value/$ terms and similar application area I'd be extremely interested in.
