[Poor boy ways]

I just bought a 95 s-10 LS ex-cab 4.6, Z vin with 186k miles and a 5 speed manual transmission.
My only real trouble is a grinding sound when i let out the clutch in first gear as it starts to roll i get a grinding noise from the transmission and you can run through the rest of the gears , even float them . I have been told everything from lose spring in the clutch assembly, to the insert gear is bad or just replace the whole thing. I can believe its trashed it just shifts to good expect for starting out. but i not a pro . So any input?
