There are a number of highly regarded lenses out there at reasonable prices, especially if you don't need fast glass. I have a kit of a K 28/3.5, K 35/3.5 (almost flare proof), M 50/1.4, M 100/4.0 macro, M 135/3.5, M 200/4.0, and an FA 300/4.5 (another legendary lens, very sharp). Bodies are a K 1000 and a Z-1p. Everything listed cost me less then $1000, actually between $800-$900 IIRC. KEH has a very good reputation on the list as does B&H.
