Last year, a Texas based holster company began making and selling canvas and leather slings for $30 which is about 1/2 the price of similar Trader Keith slings. I liked the deal and bought two from a distributor in SoCal because they sold them for less than other outlets.
I am happy with them and can not tell them from much higher priced slings. The canvas seems to fold into a smaller space than an all leather sling and fits better in my rifle take down cases.
Went to buy a couple for gifts and guess what, the maker has dropped them from his offerings. ???
