I am currently looking to add to my business for the upcoming season. I am not looking for brand wars or stories of your favorite equipment. I am simply wanting some advice on what i should look for on a more generic scale. If I were to go out and buy a straight-shaft trimmer, I can easily spend anywhere from $200.00 to $400.00 give or take before taxes. I am mostly dealing with residential grass, but having some sites on or near rivers and creeks, I do have to deal with heavier brush and weeds. my question is this, If I am out to buy a new machine, do i just buy the reasonably priced trimmer that I can convert the head to a blade if necessary for an additional 40 or 50 bucks and 10 minutes of my time, or do I splurge on the split shaft and allow myself some variability for down the road. I guess what my real question is this, is a trimmer an investment enough that I should look further along the lines than just what i am doing now? or do I save the money on a simpler machine until I have the need for anything else? As I said, I am not looking for brand wars as I have already decided on a brand. Thanks!
