Thanks for your feedback! Well, you may be surprised, but the one I used on all of the above records is, in fact, a simple headset/computer directional microphone... it says "Chateau CM-001" on it, and I doubt you could find the exact same model anywhere for it is something clearly non-brand, all the way from China. Instead, for your purpose, go for any similar dollar store mic, it would do just as well. When editing, first normalize the signal and apply noise cancelling. Then follow one of the two mastering methods described here and you should be just fine.
P.S. By no means this can compete with a Rode NT-1A thru some Great River preamp, but it's all about gaining recording experience and testing different gear/techniques.
