I just bought a new leinbach 7300 and have yet to put it together. Picked it up at thier store and the price was right. $425 including tax and auger. I think a great price. I do not have many post to set but if it is only a few it will be well worth the investment.
I have never used one and the instruction manuel does seem to not cover how to use. so I guess some on the jo training is necessary. I have found that getting older you must work smarter more that hard so if i can find any tool or equipment to make the work somewhat easier I opt for the smart way. good luck and straight digging.
