renting or buying will depend on how much use it will get. No sense buying a piece of equipment for it to sit in a yard. Rent it and return it and the rental cost is 100% shown as no profit. It cost money to maintain equipment and insure it even when not in use. I bought my Lulls new or with 50-400 hrs but have been using them all since 85, 86, 87, and 92. When paid off they are nicer to look at even all these years later. I maintain them well and they never let me down bar one breakdown that was 11,000 on the 92 machine.
I leased mine with a dollar payment at the end. The cost at the time was near or the same as a straight loan.
