I have an opportunity to get a used 3030 at a good price, but the warranty expired at the beginning of the year. The seller is a dealer and says that before the warranty expired he sent it in and had a new coil put on it. Says it runs like new. Do the 3030s have a good reputation for lasting beyond the warranty? I don't intend to do much, if any, water hunting so I'm not too concerned with the o-rings and all that.
