momacress--
Keep your eyes open to garage and rummage sales. Many times they try to sell older but very functional bikes for $5 or $10. There are a lot of utility bikes with fenders and all in the backs of people's garages.
I say that because I've had bad luck with Huffy. If you see an old Raliegh or Schwinn--consider it.
I know exactly what you mean about your desire for decent yet cheap transportation. Good for you and God bless.
