I'm starting an irrigation company and am investigating equipment. If I can find used I might go that way, but I like the Toro Dingo TX420 or TX425 w/vibratory plow attachment and I haven't found any of those used yet. My question is, how flexible are the dealers on pricing? The price I've been quoted so far (about 27k for TX420, plow, and boring unit) is pretty steep and may drive me to a used DitchWitch 255SX, which ARE available used. Thanks!
