In addition to Wayne's suggestion for what appears to be a very good, low cost solution (the Spider Pod), here's another possible choice:
I haven't used this unit (Peter Lisand's "BodyCam" model
#BCS-04) myself, but it's from a very reputable manufacturer:

B&H in NYC sells it for well within your price range.
Whichever unit you go with, if possible, try it out before making a final purchase decision.
All the best,
