I have come down to a couple options as far as getting some studio monitors. I can either stay risk-free and buy some low-end m-audios (Either Av Studiophiles or BX5) or I can buy some Event PS8 monitors off a local ad for just a little extra. The used monitors are said to be perfectly working and the only damage specified is a very small torn hole in the speaker foam near the center. My question is: Is it worth the risk to buy these nicer monitors used? I know monitors aren't something that usually is moved around a lot. I just don't want to get the cheaper monitors when I could spend the extra and get something more quality. And if I were to get them and something ends up wrong after a while, how easy are they to repair?
