I'm trying to decide on which piece of equipment to get. I really like the Plotmaster 300/400 however the price is just a little high. A local farm supply store has the Summit Plot Mule which includes disc, cultipacker, and electronic seeder for $1,300. Is there any reason why I should get a Plotmaster over the Plot Mule? The Plotmaster 300 I was looking at is $3,100 w/shipping. Opinions are appreciated!
