need a small but sturdy mic stand on the cheap? use an old spindle from a case of blank CDs. the size of the spindle should fit just about any mic clip and microphone and the large, CD sized base should be stable enough for all but the heaviest mics. if you happen to have a really heavy mic, or uneven floors, try a book, FX pedal or similar small but relatively heavy item and place it on the base of the stand for stability.
try it and let me know what you think!
