if you did not mind expanding your budget just a bit you can get the atr2500 for $66 free shipping in the usa. for $99 you can get a version which has a pop filter and nice adjustment floor stand included as these can be rather expensive!.
quality is top notch (perhaps 75-80% the quality of the well known at2020 and yeti microphones)
to mount a pop filter to the samson go you would need to use a mic stand for the go and attach the pop filter to the stand. or... you would need one of the clip on type pop filters and clip it onto whatever is nearby.
another microphone to consider is the blue snowball for $47 or a version with the metal stand for $60 but with the ice version (less features) you can hear a comparison here

if you place the microphone off to the side a bit instead of breathing/talking into it (you should be talking past it) then you might not even need a pop filter.
