Filters out the wazoo, your choice of a plethora of control software
programs (much of which is free, and some of which includes truly
superb dsp filtering, notch capabilities, digital modes, etc),
excellent construction, and for a price that would leave you with
enough left over to buy yourself another little present or two.
