I have a few jobs coming up which require that I re-edge existing beds that haven't been done in some time. I would essentially consider them starting over and am lost as to which stick edger would be best to tackle tasks like these. I will also be maintaining these edges...what I'm looking for is a good all around stick edger thats just as capable of making a new edge on a bed as it is maintaining the existing ones. I don't know if I need the most powerful one in existence, but have read past posts and people tend to look at these large displacement ones for doing new edges. The price tag of the largest ones also makes me squimish, around $500 dollars, which is a alot to spend on something that I only plan on using a handful of times every week or two. Now I've looked at stihl which many people seem to recommend, but I have used their 4-mix and just don't like it. Problem being that the straight shaft units they make seem to have the most power out of any of the other brands out there, and everyone recommends them. I'm partial to echo, they never let me down, but am wondering if the pe-311 would be powerful enough or perhaps even the pe-260 would work... Redmax, Robin, Shindaiwa, Kawasaki?
