I want to get a gas edger. I am not going to use it for business, I just want to take care of my lawn next to my house in Florida. I am looking at Echo PE-200 and PE-230 models. So my question is, is it really worth investing $100 more in PE-230 model or I will be just fine with PE-200. Why is the second model so much better that it cost so much more? I need some advice from you guys who have dealed with both models before. Thank You.
