I have been using stick edgers almost since they first came out. I have had three or four PE2400's, a Stihl back in 93 or so, a Maruyama, and most recently four Shindaiwa LE260's. What I have now has seen better days, and I am not going to sink a bunch of money into old equipment to keep it going. Anyway, I loved the Shindaiwa stuff. I still use 4 T230's, couple EB630's and the remaining LE260's. I am not real sure about the "1" series stuff with the catalytic converters, but most of all Shindaiwa is not terribly well represented around here anymore. I have exactly one piece of Redmax equipment, a little BC225DL, but I am thinking about trying a Redmax edger. I know they make both straight and flex shaft with the curved tube. The flex shaft is what I am use to. I have been using them for almost 15 years and never had a problem. I hear great things about the HEZ2500Straight though. For those who have used both, how hard is it to get used to the straight shaft after using a flex, since you are kind of holding them differently? I have never had a single problem with the flex type, so it's not like it is a durability issue for me. It looks like the straight weighs a good 2 + pounds more than the flex. I take it that is really not a huge issue? Also, what is the difference in price of the two?
