I'd also have to say if my budget was $100 I'd rather buy a used scope than buy a cheap new one. Check classifieds and even pawn shops. I know it sounds crazy but when I was younger and budgets were squeaky tight pawn shops were my main shopping spots. Although there is some risk in that I was very happy with the glass I got from pawn shops. The only draw back is they usually won't guarantee anything. But any manufacturer warantees would still be good.
