I have a Shindaiwa T231 that the shaft just broke and just replaced the seals on it b/c of losing compression so it is only time before it's gone. I would like to get a new one and have the old one as a back up. I like this weedeater as it has lasted me 3 summers working it hard. Is it pretty much how people are with Chevy and Ford or is there really a brand that is better than another. I was also thinking of just picking up a refurbished one from a company that rebuilds lawn equipment for half or quarter the price.
