Good and not expensive strings

I've never used these strings before, my only experience with Fender strings was with nickels 7250 and with flats 9050. I put them on a Fender McKagan P bass. In my opinion these steel strings are good and do not cost that much. Probably I'll buy them again in the future, but it seems that they have been discontinued ( I wonder why) and they are not easy to find anywhere.
