I am looking at a Cole Multiflex no till planter with duplex seed hoppers . Is this a good planter for sweet corn ? Other veggies ? Are plates still available from Cole ? The planter is in good shape .They want $2500. for it . Is this too much for a 2 row planter ? Would I be better to buy something else to plant sweet corn, ( 71 flex or JD 7000 units ?) .I am using a JD 290 , but I am tired of having to fix it all the time . I have a precision push seeder to plant small seeds .Thanks Tom
